Cyberattacks used to be the biggest security issue surrounding AI infrastructure, but that could be changing. A recent cargo theft outside Chicago suggests another vulnerability — and it’s one that has nothing to do with malware or prompt injection.
Just last week, the Cook County Sheriff’s Office recovered two stolen trailers containing roughly $1.3 million in data center equipment and copper wiring, taken from separate shipments originating hundreds of miles away. One trailer held about $300,000 worth of copper wire — reported stolen in Pine Hill, Alabama — destined for data center construction. The other carried roughly $1 million in data center infrastructure equipment, stolen out of Jacksonville, Florida. Both ended up at the same truck yard in Elk Grove Township, outside Chicago.
Viewed in the context of the AI boom, it highlights that the physical supply chain itself is becoming a new target for bad actors.

A new high-value cargo
We’re all familiar with typical bottlenecks like GPU shortages, power constraints and cooling capacity, which have plagued the AI era since its inception. But we forget that building an AI data center requires an enormous volume of specialized hardware moving through freight networks. These include servers, networking gear, fiber, switchgear, cooling systems, power distribution equipment and thousands of pounds of copper. Each represents capital investment and potential deployment delays.
As hyperscalers accelerate the construction of data centers, the exposure of these items between the factory and data center creates a risk category that the industry as largely ignored.
When one delay cascades
Large GPU clusters depend on the synchronized delivery of dozens of interconnected systems. A training cluster is a tightly coupled system of servers, switches, optics, power distribution, and cooling that must be installed together. Missing networking hardware can idle racks, delayed power equipment can postpone an entire deployment and stolen copper can stall electrical work. So when one component category disappears, the delay cascades across everything.
So when one component category disappears, the delay cascades across everything.
Cargo theft by the numbers
Infrastructure resilience increasingly depends on whether critical hardware arrives at the construction site at all — and on schedule. Verisk CargoNet reported that U.S. and Canadian cargo theft losses jumped roughly 60% in 2025 to nearly $725 million, even as the total number of incidents held essentially flat — a sign that thieves are becoming more selective about high-value freight. Metal theft rose 77%, driven largely by demand for copper, while organized groups shifted toward enterprise computing hardware. CargoNet expects that focus on high-value technology — RAM modules, storage drives and enterprise computing equipment — to carry into 2026. For broader context, the Department of Homeland Security has estimated that cargo theft overall costs as much as $35 billion a year.
The Chicago incident fits squarely inside that trend.
Beyond firewalls and malware
Obviously, cargo theft isn’t an engineer’s problem. But organizations building AI infrastructure may need to broaden their thinking about deploying AI capacity on aggressive timelines.
Cloud providers, colocation operators and hardware vendors have already invested heavily in defending infrastructure from digital threats. As AI infrastructure becomes more valuable, protecting the physical systems behind it may deserve similar attention.
The next supply-chain conversation
The AI boom has already forced the industry to rethink electricity, cooling, networking and semiconductor manufacturing. Physical logistics may be next.
It starts long before the equipment reaches the data center.
If the value of AI infrastructure continues to climb into the billions of dollars, the industry’s definition of “infrastructure security” is likely to expand beyond firewalls and identity management. It starts long before the equipment reaches the data center.
Microsoft’s latest AI services announcement suggests the era of standardizing on a single model may be ending. This week, the company launched a $2.5 billion AI adoption business designed to help enterprises customize AI deployments and use multiple models rather than lock themselves into a single provider — part of a larger shift toward systems that route each request to the model best suited to the task.
Simply put, the company that arguably has the deepest single-model partnership in the industry is now selling model swappability as the product.
Betting $2.5 billion on flexibility
Microsoft said Thursday it is creating a new operating entity, Microsoft Frontier Company, to help corporate customers select AI technologies that actually work for their businesses and produce a return on investment, Reuters reported. The unit launches with $2.5 billion in funding from Microsoft and will work with customers including Unilever and Novo Nordisk.
The new firm will help customers choose and integrate AI tools — from Microsoft and external providers — with each customer’s internal data. Customers will own the results of that work rather than handing it back to Microsoft. The move puts Microsoft alongside Palantir, which is doing similar work with large customers using Nvidia’s open-source models, and Amazon Web Services, which recently launched a $1 billion embedded-engineering unit of its own.
What’s most telling is the reasoning. Judson Althoff, CEO of Microsoft Commercial Business, told Reuters the new firm grew partly out of Microsoft’s own experience watching models like DeepSeek and Google’s Gemini catch up to OpenAI. Referring to the original Copilot, he said, “we made a mistake by binding it to OpenAI models only.” Customers, Althoff said, care more about the combination of their data and the models than about any particular model — and they need the ability to swap models quickly as the state of the art shifts.
“We made a mistake by binding it to OpenAI models only.”
One model no longer fits
Consider a typical customer service application that might need to summarize a support ticket, analyze a 300-page contract, generate an email, transcribe a meeting and review source code. Those aren’t necessarily the same problem. A model like Google’s Gemini, with a context window of a million tokens or more, may be the right choice for the contract. A small, fast model like OpenAI’s GPT-5.4 mini or Anthropic’s Claude Haiku may handle ticket summaries at a fraction of the cost. The transcription may go to a purpose-built model like Whisper. And if regulators require customer data to stay on-premises, an open-weight model like Meta’s Llama or Mistral is often the preferred choice.
Instead of choosing a single foundation model, developers increasingly choose several — and the application decides which one handles each request.
AI gateways become core infrastructure
The model is just one component of the stack, so the decision to route the request has to live somewhere. That’s why developers are forgoing hard-coding an application to a single model and building systems that can choose among several. The routing logic might prioritize cost for one request, speed for another, or keep sensitive workloads on a local model. That way, if one provider experiences an outage, traffic can be routed elsewhere without changing the application itself.
The company that arguably has the deepest single-model partnership in the industry is now selling model swappability as the product.
That changes what developers build
Once companies stop relying on a single model, the challenge shifts to building the systems that decide which model to use for each request.
That means developers need tools to route requests, compare model performance, monitor reliability, control costs, enforce security policies and switch to another model if one goes down, which is a very different engineering problem, especially since deciding which model should respond to a request occurs every time someone uses your application. At enterprise scale, those decisions happen millions of times a day, so they have to be fast, reliable and easy to manage.
The ecosystem is already responding
Open-source proxies like LiteLLM and gateways like Portkey normalize APIs across providers. Orchestration frameworks such as LangChain and LangGraph assume the presence of multiple models from the start. The Model Context Protocol (MCP) is making tool integrations portable across models rather than bound to one vendor. And the cloud providers themselves — Amazon Bedrock, Azure AI Foundry, Google Vertex AI — now expose many models behind a single API.
Orchestration is the new moat
Core models will keep improving. But as performance converges for many business tasks, orchestration becomes the challenge. Microsoft’s announcement is one indication that the largest vendors believe enterprises are heading in that direction and are willing to spend billions to be the ones holding the routing layer.
Instead of treating the model as the platform, enterprises are consistently treating it as a replaceable component behind an orchestration layer.
The cloud era taught developers not to tie applications too tightly to one server; containerization made infrastructure portable. Now the same philosophy is being applied to AI. Instead of treating the model as the platform, enterprises are consistently treating it as a replaceable component behind an orchestration layer.
When Subquadratic launched earlier this year, it could build a sparse-attention model that could handle a 12-million token context window and be significantly faster than today’s large language models. But it didn’t launch the model widely and it didn’t publish benchmarks.
Given the company’s large claims, that created quite a bit of skepticism. In June, Subquadratic published its first model card and benchmarks for its small model, SubQ 1.1, supplied third-party verification from data firm Appen, and started talking about its first design partners who now have access to its model.
So far, however, few people have actually used its model. To talk about the company, why its model isn’t widely available yet, and what it has in store for the near future, we met up with Subquadratic co-founder and CTO Alex Whedon.
“We’re not a sparse attention company either.” — Alex Whedon, Subquadratic.
One thing Whedon definitely wanted to clear up is that the company’s current model may be based on sparse attention, but that isn’t its full mission.
“We’re not a sparse attention company either,” Whedon tells The New Stack. “We’ve been working on non-attention architectures for quite a while as well. We think that we will be the first people to leapfrog ourselves in terms of the next model architecture.”
We’ll get back to that.
What the model card shows
It’s the company’s SubQ 1.1 Small model that people are talking about now. This model is built on Subquadratic Sparse Attention (SSA), an attention mechanism the company says scales close to linearly with context length instead of quadratically.
“In the case of Subquadratic Sparse Attention specifically, which is one of a couple model architectures we worked with, the idea is that not all of the token relationships matter,” Whedon explains. “Token relationship compute is why you see this quadratic scaling law.” This means there are almost a million possible two-token relationships in a 1,000-token input in a full attention matrix.
For SubQ 1.1 Small, the strongest results are in long-context retrieval, which makes sense, given that this is where the architecture should have its biggest edge.

On the needle-in-a-haystack test, SubQ 1.1 Small scores near-perfect from 1 million tokens out to 12 million, even though it was trained mostly at 1 million. It hits 99.12 percent on Nvidia’s harder RULER test, which asks the model to trace and aggregate facts across a 128,000-token context rather than just find one.
On general capability, it lands just below the mid-tier frontier models, at 85.4 on GPQA Diamond against 87.5 for Sonnet 4.6. On the LiveCodeBench coding benchmark, it scores 89.7, below Opus 4.8 and GPT-5.5, but slightly better than Sonnet 4.6.
Efficiency is where the model shines, though. The company says that at 1 million tokens, SubQ uses 64.5x less compute than dense attention and runs 56x faster than FlashAttention-2 on a single attention layer. At the full 12-million-token window, it puts the attention compute reduction at close to 1,000x.

“Even in full dense attention, the relative importance of over 99 percent of tokens is very low, attention scores are below 0.1,” Whedon says. “We actually show this in our model card. So clearly we’re just wasting compute most of the time, and in fact we’re maybe making the modeling task harder, because we’re introducing noise.”
“Transformers are a brute-force approach to the problem of text modeling,” he says. “You could say, ‘I’m going to compare every single individual token to every other possible individual token.’ That’s what transformers do. Very brute force, very naive. It just assumes that the first needs to look at the second, the third, the 50th, and the 5,000th. That’s not how humans read text.”
SSA also differs from retrieval-augmented generation, which drops chunks of text before the model sees them. “Every token of the text is being seen by the model,” he says. “It’s just not being redundantly compared to every other token of the text.”
On capability, SubQ 1.1 Small lands roughly in Sonnet 4.6 territory, sometimes a bit above, sometimes below. But its edge, the company says, is size and cost.
“What we posted publicly was fewer than 100 billion parameters,” Whedon says about the size of the model. “I would venture to say that our model is smaller than any of the models offered by OpenAI or Anthropic. But our next model will not be.”
Smaller, cheaper, built for enterprises
Subquadratic is also making the pitch that its model’s capabilities will be especially interesting for enterprises.
“We think that’s a pretty interesting enterprise offering,” he says. “We’ve seen a lot of people in the enterprise space talking about using the mid-tier models as opposed to the frontier for large data-processing tasks, which is exactly where we’re trying to plug in.”
Given that a lot of enterprise problems start with searching through large heaps of data, this makes sense. You can pack a lot of documents into a 12-million token context window, after all. Most of today’s models break down well before the user fills their million-token windows, but with its near-perfect retrieval scores, SubQ may be a good answer for these problems.
As Whedon noted, the model’s first users are design partners, not the public. “We’re giving access to the model to design partners now, and these are mostly enterprises, largely with eight- to nine-figure spend,” Whedon says. “This is a core market that we really care about. It has been since day one.” A limited individual-access release will follow before any general availability.
The launch led with claims instead of benchmarks by choice.
“We were announcing mostly research,” he says. “We could have maybe messaged the launch a little bit differently. There was some debate about how we were going to message it.”
Built on an existing model
One question from May hasn’t gone away, though. The model card states that Subquadratic “started with an existing open-weight frontier model by replacing its dense attention with Subquadratic Sparse Attention (SSA),” and then ran roughly one trillion tokens of long-context continued pretraining on books, documents, and repository-scale code.
That confirms what some of the skeptics suspected at launch, when OpenAI researcher Will Depue wrote that SubQ was “almost surely a sparse attention finetune of Kimi or DeepSeek.” What’s new here then is the SSA mechanism and the long-context training recipe, not a model trained from scratch. The company has not said which open-weight model it started from.
The biggest lever on long-context retrieval was pretraining on very long sequences, Whedon says, something SSA’s efficiency made cheap enough to run as routine.
“Nobody’s talking about multimillion-token pretraining,” he says.

Why hybrids don’t go far enough
There have, of course, been attempts to improve on quadratic scaling, but Whedon thinks most of those attempts only go — almost literally — halfway. Hybrid models such as Nvidia’s Mamba-based Nemotrons, Qwen’s Gated DeltaNet layers, and the various linear-retention designs swap out some of the attention layers, but they don’t go all the way.
“If 80 percent of the layers are not quadratically scaling, then your maximum payoff is like a 5x increase as you scale toward infinity,” he says. “We see a 60x increase at 1 million tokens, almost 1,000x at 12 million. That is the type of payout that you only get if you actually change the scaling law, as opposed to a scalar win.”
He actually credits DeepSeek’s own sparse attention mechanism with making his company’s pitch easier.

“They showed that you could dynamically select relationships without a significant quality trade-off,” Whedon says. “However, they did so by redundantly using a smaller but still full-attention model that ends up using the vast majority of the compute at scale.”
Subquadratic ran its own benchmark against GLM 5.2. “At 1 million tokens, 58 percent of the prefill latency comes from that selection mechanism,” Whedon says. “So that selection mechanism, which is supposed to be seen as cheap, actually dominates the compute, because it’s a quadratically scaling component.”
Beyond sparse attention
It’s also why Whedon pushes back on the “sparse attention company” label. Subquadratic has been working on what he calls “zero attention,” architectures that drop the attention mechanism altogether.
“Attention is kind of similar to RAG in that you have queries, keys, and values that represent information about the tokens that you’re processing,” Whedon says. “There’s this discreteness of representation, where everything is represented within these nice little boxes. That’s super convenient. It’s easy to build a brute-force solution around it. But it also means your ability to compress information is limited. If you had a more continuous, abstract way of representing the information, then you could compress it further, which means you can make smaller models, or you could just scale things up again to create another leap in intelligence.”
He traces the idea to world models and to Yann LeCun’s work. “The stuff we’re doing takes a lot of inspiration from world models, not the video modality in this case, but some of the things LeCun is talking about,” he says. “Rethinking how to represent long-range dependencies, how to keep a long-range state, how to rethink the objective function.” He stops there. “That’s probably all I could say for now.”
Subquadratic has also marketed only one of the three kinds of efficiency it says it is chasing. “We care about compute, sample, and memory efficiency,” Whedon says. “We’ve done a lot of work on all three, but have only really talked about the compute efficiency publicly.”
The near-term plan
The near term plan for Subquadratic, however, is more modest. “Over time, yes,” Whedon says, when asked whether Subquadratic could rival OpenAI and Anthropic on raw quality in the long run. “In the shorter term, we have to be strategic. If we try to boil the ocean on much less capital, it’s not going to go well for us.”
The next model, he says, will likely be a mid-tier size rather than a frontier-class one (think SubQ 1.2 Medium), that he expects to outperform most of the competition in its tier.
How the team will bring the model to market, though, remains to be seen. I wouldn’t be surprised if the team launched its model on one of the hyperscaler’s large model platforms, but Whedon remained tight-lipped about the company’s plans.
The fact that we met with the Miami-based Whedon in San Francisco, though, gives you a bit of a hint of what the team is currently up to.
OpenClaw finally dropped its iOS and Android apps this week, meaning you can now ditch the Telegram and WhatsApp methods to talk directly to your personal AI agent. But what’s arguably more exciting is that the app isn’t actually running the AI on your phone. It’s just hooking up to an agent you’ve already got running somewhere else. Your phone now acts as a window into that agent, complete with voice, notifications, and camera access.
It’s a nice design choice, and exactly where personal AI agents are headed.
Phones become authenticated endpoints
The phone is basically becoming a really smart remote control for OpenClaw. Instead of cramming an increasingly powerful agent onto a phone with battery and memory constraints, developers are treating the phone as one more screen for an agent that lives elsewhere. The agent keeps working whether your phone is in your hand or charging in the other room.
Within this model, the phone approves actions, pings you with notifications, lets you talk to the agent, and shares your camera when the agent needs eyes on something.
Persistent runtimes replace mobile constraints
But OpenClaw isn’t the first to do this. Anthropic’s Claude Cowork with Dispatch follows a remarkably similar pattern. Users assign work from their phones, but execution occurs on a persistent desktop runtime. The mobile app acts as a companion for starting tasks, monitoring progress, and receiving results rather than becoming the agent itself.
OpenAI is moving in a similar direction as well. With Codex, developers increasingly interact with long-running coding agents that continue working independently and can be checked on from multiple clients, instead of treating the phone as the place where the agent runs.
Different companies, different products, but a similar architectural bet to keep the agent running in a persistent runtime and give people lightweight clients to interact with it.
When multiple teams independently converge on the same architectural pattern, it’s often an early signal that the industry has found a model that solves a real engineering problem.
The engineering problems are totally different now
This shift changes what developers spend their time thinking about. Building mobile apps used to mean worrying about battery life, memory limits, offline mode, and squeezing the best performance out of a phone. If the agent is running somewhere else, most of those concerns fade into the background.
Now, a new set of questions comes to mind, such as how a phone securely connects to a long-running agent? How do you manage permissions across multiple devices? What happens if every client disconnects but the agent keeps working?
Agent identity beyond login screens
There’s a downstream effect here. Once the phone is just one of several trusted endpoints talking to your agent, you need a much more robust approach to identity. You’re not logging a user into an app anymore. You’re authenticating devices into an ongoing relationship with a persistent agent.
As that agent gains the ability to read your files, send emails, call APIs, and control external tools, authentication becomes load-bearing infrastructure.
Distributed agents reshape developer tooling
Zooming out a bit and looking at the bigger picture highlights how personal AI agents increasingly resemble distributed systems rather than mobile apps. The intelligence lives in a persistent runtime while the phone is one authenticated endpoint among several.
For developers, the mobile app is only part of the job. They also have to build the components that keep an agent running, connect it to a user’s devices, and ensure those connections remain secure.
The agent keeps running independently, while the phone is simply another place to check in, approve actions, or start a conversation.
Looking at OpenClaw alongside Anthropic and OpenAI, it’s hard not to notice the same pattern. The agent keeps running independently, while the phone is simply another place to check in, approve actions or start a conversation. That architecture solves many practical problems, which may explain why several companies are heading in the same direction.
AI has changed the web right before our eyes. With Google’s AI Overviews doing the heavy lifting, publications that once owned the first page of search results are being replaced by summaries. Readers get their answer without ever clicking through. Much of the traffic has simply stopped.
Cloudflare on Wednesday announced a slew of updates for publishers who are facing this new reality. From new crawler classifications and analytics dashboards to Answer Engine Optimization tools and an expansion of its Pay Per Crawl program, it’s clear the company is trying to become the economic pipes of the AI web.
The shift from ‘keep out’ to ‘let’s make a deal’
A year ago, Cloudflare’s pitch was practically defensive, asserting that website owners should be able to block AI crawlers. And while that still holds true, the company has pivoted to discussing building “rails” for an “agentic economy.” And it makes sense. If AI agents are already browsing the web, collecting content, and in some cases buying things, someone needs to handle the business end of how the sites they visit are compensated. Cloudflare thinks that someone should be Cloudflare.
Paying for value, not visits
Roughly a year ago, Cloudflare launched Pay Per Crawl, which let publishers set a price for AI companies to pay when they fetched a page. Now the company is pushing toward Pay Per Use, which means publishers get paid when their content actually appears in an AI-generated answer.
To backtrack, under the old model, an AI crawler pays to visit your site, whether or not it does anything useful with what it finds. Cloudflare says it’s already testing this with Ceramic.ai and You.com, each running slightly different versions of the concept.
Instead of charging for access — which is basically a toll booth — publishers are charging for value.
The economics here flip. Instead of charging for access — which is basically a toll booth — publishers are charging for value. That’s closer to how affiliate marketing or licensing deals work, and it’s a much harder problem to solve. It requires knowing which content contributed to which answer, which means an attribution infrastructure that doesn’t really exist at scale yet.

Crawlers need clearer labels
But here’s where things get more technical — and a bit political.
Cloudflare wants AI companies to stop lumping all their crawlers together. Right now, a single bot from a major AI company might be fetching pages for search indexing, model training, and agent tasks all at once. That makes it impossible for site owners to say yes to one use and no to another.
Starting September 15, Cloudflare plans to change the defaults for new and free-tier sites. AI search crawling stays on, but training and agent access get blocked on ad-supported pages unless the site owner opts in. Mixed-use crawlers that refuse to separate their traffic get blocked entirely.
The company is clearly taking a shot at Google here, noting that Google’s bundled approach gives it access to roughly twice as much content as AI-native competitors. Separating crawlers’ intent has become a prerequisite for any kind of functioning market between publishers and AI companies. Because if site owners can’t distinguish between “index my page for search” and “train your model on my writing,” they’ll increasingly just block everything.
Separating crawlers’ intent has become a prerequisite for any kind of functioning market between publishers and AI companies.
Optimizing for AI answers
Cloudflare is also rolling out a dashboard designed for business teams, called Attribution Business Insights. Think of it as the AI equivalent of knowing your Google Search Console numbers, except the “search engine” is now ChatGPT or Perplexity or whatever agent your reader happened to ask.
On top of that, Cloudflare is introducing Answer Engine Optimization (AEO). The idea is that ranking in Google is no longer enough; for publishers to succeed, they also need to understand how and where their content gets cited in AI-generated responses. That’s a different optimization problem than SEO, and right now almost nobody has good tooling for it.
Infrastructure as competitive advantage
Cloudflare already sits between websites and the internet. It sees the traffic and knows what changed on a page and what didn’t. It can tell a crawler to come back later because nothing’s new, which, by the way, it says would eliminate over 50% of current AI crawl traffic.
That puts Cloudflare in a unique position. It’s already part of the path between AI companies and the web. Now it wants to become the layer that manages access, attribution, and eventually payments between them. If AI agents become the primary way people find information online, Cloudflare is betting the next battle won’t be over who builds the smartest model but instead over who builds the infrastructure everyone else relies on.
If AI agents become the primary way people find information online, Cloudflare is betting the next battle won’t be over who builds the smartest model — it’ll be over who builds the infrastructure everyone else relies on.
For two years, the AI infrastructure race has been dominated by one question: Who has the fastest GPU? Jim Keller thinks that’s becoming the wrong question.
In a recent interview with EE Times, the Tenstorrent CEO argues that the riskiest move an organization can make right now is optimizing its AI infrastructure for the models it’s running today. It’s not because those models are bad — but because they won’t be the models it’s running in 18 months. Keller invoked Rent’s Rule and Amdahl’s Law to argue that memory, networking, and system-level balance now matter more than peak floating-point performance.
Not because those models are bad — but because they won’t be the models it’s running in 18 months.
It sounds like the start of Keller’s product pitch, but there’s real weight behind it, because AI has evolved faster than the infrastructure underneath it. And the companies that spent hundreds of millions building around one generation of models are now staring down the cost of doing it all over again.
That fear is called lock-in, and it’s reshaping how the biggest players in AI think about hardware.
Workloads outgrew the GPU
In 2023 and 2024, AI infrastructure was a relatively simple procurement problem: Train large language models, serve them to users, and buy as many GPUs as Nvidia can ship. The workloads were predictable and GPUs handled them well.
Then AI outgrew the infrastructure it had been built for.
Reasoning models spend more time working through problems instead of jumping straight to an answer. Agents bounce between APIs, databases and code before completing a task. Multimodal models mix text with images, audio and video. None of those workloads stress hardware in quite the same way — and that’s forcing infrastructure teams to rethink assumptions that made perfect sense just two years ago.
AI outgrew the infrastructure it had been built for.
No single chip architecture handles all of that equally well. And the organizations building AI infrastructure are starting to realize that the question isn’t just which accelerator is fastest — it’s how do we build systems that won’t need to be torn apart every time AI takes another leap?
Nvidia is already selling one answer
Look at what Jensen Huang has been talking about, and it’s not GPUs anymore.
At GTC 2026, Nvidia unveiled the Vera Rubin platform — seven chips designed to operate as a single system: the Rubin GPU, Vera CPU, NVLink 6 switch, ConnectX-9 networking, BlueField-4 DPU, and more. The Vera CPU exists
for the CPU-intensive work of agentic AI — tool calls, code execution, orchestration. Nvidia calls these deployments “AI factories,” and the language is deliberate. They’re selling complete infrastructure, not individual accelerators.
When the company with 70% market share stops leading with GPU benchmarks and starts talking about system-level co-design, it tells you where the center of gravity in this market is moving.
That reframing matters. When the company with 70% market share stops leading with GPU benchmarks and starts talking about system-level co-design, it tells you where the center of gravity in this market is moving. Compute still matters. But Nvidia is conceding — through its product architecture if not its marketing — that raw accelerator performance alone won’t be enough for what’s coming.
Hyperscalers design their own silicon
AMD sees the same problem, even if it’s taking a different route. Helios brings together CPUs, GPUs and networking into one rack-scale platform, reflecting a broader shift away from treating the GPU as the center of the universe. The pitch isn’t “our accelerator is faster.” It’s that the infrastructure surrounding the chip increasingly matters just as much as the chip itself.
The hyperscalers have been making this argument with their wallets for even longer. Google has spent a decade co-designing its TPU silicon, interconnects and software framework — its seventh-generation Ironwood chip is now generally available — giving it unusual control over the full stack. Amazon went the opposite direction, building separate chips for separate jobs: Trainium for training, Inferentia for inference, with Trainium3 now in production and serving customers like Anthropic. Microsoft’s Maia 200 targets inference costs, while the company simultaneously deploys Nvidia’s Vera Rubin NVL72 for training and experimentation — arguably the most pragmatic dual-track strategy in the market.
Behind all of them sits Broadcom, whose AI semiconductor revenue recently crossed $10 billion in a single quarter, driven by staggering demand for custom accelerators and data center switches. Broadcom designs custom accelerators for Google, Meta and others while supplying the Tomahawk and Jericho switch silicon that connects those accelerators at data center scale. Custom ASIC shipments are projected to grow roughly 45% year over year in 2026 — triple the growth rate of merchant GPUs.
Then there are the companies that decided building a better GPU wasn’t the answer.
Cerebras questioned the need for thousands of interconnected chips, opting instead for a wafer-scale processor that keeps far more of the workload on a single piece of silicon. Groq took the opposite approach, optimizing almost entirely for inference. SambaNova focused on enterprise AI, building systems where efficiently serving multiple models matters more than posting the fastest benchmark.
Adaptability beats raw speed
The first wave of generative AI rewarded whoever could buy the most compute. That made sense when most organizations were solving the same problem. Today, AI workloads are changing so quickly that infrastructure teams are starting to optimize for something different: adaptability.
Keller’s example illustrates the point. Tenstorrent’s BlackHole architecture uses standard Ethernet instead of proprietary interconnects, allowing its hardware to slot alongside existing GPU deployments rather than replacing them. Keller told EE Times that one customer used Tenstorrent’s Galaxy servers to increase token throughput on GPUs they already owned instead of rebuilding their infrastructure from scratch.
Whether Tenstorrent’s approach becomes the industry standard is almost beside the point.
The bigger idea is already spreading. Across the industry, companies are spending less time asking how to build the fastest AI hardware and more time asking how to build hardware that won’t have to be replaced every time AI takes another leap forward.
The question that matters now
No one knows what AI workloads will look like three or five years from now. That’s the problem.
Infrastructure refresh cycles are measured in years. AI models seem to reinvent themselves every few months. Building around today’s workloads is starting to look like a risky bet when tomorrow’s could demand something different.
Infrastructure refresh cycles are measured in years. AI models seem to reinvent themselves every few months.
Every company is responding in its own way. They have different strategies but are still asking the same question: How do you build infrastructure that outlasts the AI running on it?
That may prove to be a more important engineering challenge than building the next record-breaking accelerator. And it’s the challenge driving companies from Nvidia and AMD to Google, Amazon, Broadcom and Tenstorrent.
Amazon EKS runs hundreds of thousands of Kubernetes clusters across more than thirty AWS regions. Operating at that scale has taught us something that has shaped how we build the service and that we think is useful to anyone running Kubernetes at scale: most availability problems do not stem from a component failing. They come from a component reacting to a problem in a way that makes it worse. A cache that goes stale and serves wrong answers. A health check that restarts the very process keeping a cluster alive.
What separates a resilient control plane from a fragile one is not the number of faults. It is whether a fault stays a fault or becomes an outage. This post is the story of how we keep the EKS-managed Kubernetes control plane on the right side of that line at ever-growing scale: the foundational changes we made and why, and what operating at fleet scale taught us about building systems that tolerate faults rather than spreading them. These are the reasons our most demanding customers confidently run their mission-critical workloads on EKS.
How AI and analytics workloads reshaped what “scale” means
Kubernetes was built for a particular rhythm of work. Pods came and went at predictable rates, and controllers had seconds or minutes to reconcile. The system’s design reflected that pace: strong data consistency, ordered watches, and consensus-replicated storage that puts correctness first. It worked beautifully for what it was designed to do, and it still does.
“What separates a resilient control plane from a fragile one is not the number of faults. It is whether a fault stays a fault or becomes an outage.”
But the workloads evolved faster than anyone anticipated. Foundation model training runs scale-up training jobs on thousands of GPU nodes in minutes. Real-time inference services scale from a warm baseline to thousands of replicas, then drop back within the hour. Apache Spark analytics pipelines burst from zero to tens of thousands of executor pods, chew through a dataset, and vanish.
Emerging agentic AI workloads add yet another dimension: autonomous agents that spin up, fan out, execute tasks, and tear down in seconds or less. These workloads share a trait that distinguishes them from traditional microservices: they generate enormous volumes of state transitions within compressed time windows and are deeply intolerant of delays. This velocity of state change pushed us to reinvent some of the mechanics to support a scale that was previously impossible, and to contribute what we could upstream.
How EKS reimagined Kubernetes storage foundation
Every Kubernetes cluster depends on etcd as its source of truth. Every application, every service endpoint, every scheduling decision is stored there. If etcd loses data, the cluster forgets everything it knows. Protecting that state is the most important job for a managed Kubernetes service.
Operating etcd for one cluster is well understood. Operating it for a fleet of millions is a different problem entirely. Hardware fails, networks blip, and disks degrade, so something has to handle those events without a human in the loop. And the operations etcd needs most, like replacing a failed member or recovering after a zonal event, are exactly the ones where a person acting under pressure can make a mistake that causes permanent data loss.
From the beginning, we built an operator agent that runs alongside every etcd instance and automates its entire lifecycle. The agent has two jobs. First, backup and recovery: it takes point-in-time snapshots and stores them durably outside the cluster. If too many instances are lost at once and the survivors cannot form a majority, the agent automatically detects the condition and rebuilds from the latest snapshot. Second, membership management: when an instance fails, the agent removes the terminated member and adds its replacement in an order that protects quorum and prevents split-brain.
A recent, more fundamental change was replacing etcd’s consensus mechanism, Raft, with a purpose-built journal that provides durable, ordered storage independently of etcd. In traditional etcd, a majority of members must agree on every write before it is committed. If two of three are unhealthy, the cluster becomes unavailable.
By offloading durability to the journal, etcd peers no longer negotiate quorum among themselves. Writes commit as soon as the journal acknowledges persistence, and that entire class of etcd quorum-loss failures disappeared. Since the journal handles persistence, etcd no longer needs to fsync writes to local disk, so its data store has moved to an in-memory filesystem. What was a disk-bound system became a compute-bound one, and storage latency was removed entirely from the critical path. For a deeper look at this architecture, read “Under the hood: Amazon EKS ultra scale clusters.”
“What was a disk-bound system became a compute-bound one, and storage latency was removed entirely from the critical path.”
For ultra-scale clusters, we went further and partitioned etcd into resource-specific shards. Each partition operates independently with its own storage budget and throughput capacity. The primary value is failure isolation. In a monolithic deployment, if the events keyspace exceeds its quota because a misbehaving controller creates objects faster than garbage collection can remove them, it blocks writes to everything, including node leases.
Suddenly, healthy nodes appear unhealthy because their lease renewals are being rejected. With partitioned etcd, the events partition hits its quota, but the leases partition continues operating normally. Nodes remain healthy. The scheduler keeps running.
What replacing etcd’s consensus mechanism unlocked
Removing the quorum requirement allowed us to make a change we had wanted for a long time: running etcd on the same host as the API server. In the traditional layout, every read and write crosses the network between separate machines. Each trip is fast on its own, but at thousands per second, the travel time adds up. With collocation, the API server talks to its local etcd over a loopback interface, and pod scheduling and controller reconciliation get measurably faster. For workloads where job controller queue depth is the binding constraint, shaving milliseconds off each API call means many more jobs are processed per second before the queue starts growing.
This is where the operator agent paid off. When etcd runs on the same host, an etcd member comes and goes whenever a control-plane host is replaced, which happens routinely. That only works if membership management is completely safe and automatic, which is exactly what the agent was already doing. We did not have to build a colocation from scratch; we built it on top of infrastructure that had been managing etcd membership safely since day one.
Collocation also taught us a lesson worth passing on: the convenient path needs a failover in case it breaks. The local etcd is the fast path, but if it becomes impaired, the API server fails over to another etcd member that is actively serving other API servers from the same journal. When you optimize for the common case, design just as deliberately for the moment that optimization is not available.
Fixing bottlenecks across the stack
At extreme scale, you have to address bottlenecks across the entire Kubernetes stack, and most of them are not bugs in the traditional sense. They are design choices that were correct at the scale Kubernetes originally targeted and break down only when the numbers get large. Rather than working around them internally, we fix them upstream so the entire community benefits.
One example involved the watch cache, the in-memory layer that distributes state changes from etcd to every controller watching for updates. When a controller starts, it requests a full snapshot of the current state via a mechanism called WatchList, and the existing implementation holds a shared read lock for the duration of the response build.
At hundreds of thousands of objects, that work runs long enough to starve the writer that needs exclusive access, so the cache’s resource version cannot advance. Consistent reads see a stale cache and fail over to etcd, while the response building churns through hundreds of thousands of allocations under the lock. We identified this as a limitation in the watch-cache’s locking model and are working with the community to refactor the underlying data structures and interfaces to eliminate the contention.
The same shape appears elsewhere. In the Horizontal Pod Autoscaler, a single mutex protecting the scaling state becomes a serialization point at high HPA counts, where workers spend nearly all their time blocked rather than doing useful work. A redesigned data store (PR #139142) restores parallelism and raises reconciliation throughput by orders of magnitude. In the scheduler, we identified a bottleneck (issue #138426): every scheduling cycle rebuilds a set of in-use persistent volumes by scanning every node in the cluster, even for pods that do not use storage at all. The fix computes that information lazily, and only for pods that actually need it, restoring throughput at scale.
Each of these started from a real production workload hitting a cliff, and we are working on the fixes upstream so the improvements reach every Kubernetes user.
From engineering to guarantees: EKS Provisioned Control Plane
The engineering described above made the EKS control plane more resilient and performant. But customers had a different problem: they could observe that the control plane kept up today, but they could not reserve its capacity the way they reserve compute or GPU capacity.
A team planning a thousand-node training run could secure the instances weeks in advance, yet had no equivalent mechanism for the orchestration layer that would coordinate them. EKS Provisioned Control Plane fills that gap. It exposes the control plane’s performance as dimensions you size explicitly, backed by the same kind of commitment you expect from the rest of your infrastructure.
You choose a scaling tier that maps to concrete, measurable capabilities: API request concurrency, pod scheduling rate, and cluster database size. The tiers range from XL through 8XL. At the top end, 8XL on Kubernetes 1.34 provides 16,000 concurrent API request seats, 400 pods-per-second scheduling rate, and 16 GB of cluster database storage, all backed by a 99.99% availability SLA measured in one-minute intervals.
Tiers are not static. You step up before a GPU training run or a large sales event, step back down during quiet periods, or grow permanently as your platform matures. Configuration happens through the console, CLI, eksctl, CloudFormation, or Terraform on any cluster, without recreation or downtime.
For AI workloads, orchestration capacity is planned alongside GPU capacity, available when the compute comes online. For analytics platforms submitting hundreds of jobs per minute, the control plane is ready for the burst before it arrives. And for organizations that need environmental consistency across staging, production, and disaster recovery, the same tier guarantees consistent performance characteristics everywhere.
Taking the same foundation to the edge
Some workloads cannot move to the cloud, whether due to data sovereignty requirements, latency constraints, or unreliable connectivity to the Region. Running Kubernetes in these disconnected environments introduces unique challenges: etcd must remain durable on hardware with only a few machines, the cluster must self-heal without reaching the cloud, and observability must survive network partitions that last days.
With the updated architecture for EKS local clusters on instance store Outposts, we brought edge clusters onto the same management plane and software stack as EKS clusters in the cloud.
The control plane lives in an EKS-managed account on the Outpost rather than in the customer’s account, so customers never manage control plane instances, etcd backups, or logging agents themselves, and they cannot accidentally break the thing keeping their cluster alive. The same machine images, container images, and operator agent run in both places, with edge-specific behaviors selected by configuration.
Because it is the same stack, new Kubernetes and EKS platform versions arrive in lockstep with their cloud release, and features like EKS add-ons, Pod Identity, and access entries work the same way they do in a Region.
The hardest part was keeping etcd healthy on hardware with only a few machines that may be cut off from the cloud for days at a time. We solved it by extending the same agent. It keeps a spare copy of the data continuously up to date and promotes it the instant a machine fails, so the cluster heals itself with no human involvement and no connection to the cloud.
Observability survives the disconnect, too: the metrics agent continues collecting and writing to local disk, shedding the least critical data first when space runs short, so the signals that matter most are the last to go. When the link returns, the buffered data is flushed back with its original timestamps.
All of this only works because the system was designed from the start to operate without anyone logged in. That same design is what makes it possible to deploy changes safely across the entire fleet.
Operating safely at fleet scale
Every one of these changes was deployed to a running fleet of hundreds of thousands of clusters. The journal migration and collocation required transitioning each cluster individually. Every migration follows a strict sequence: validate pre-conditions, create a point-in-time snapshot, perform the switchover, validate post-conditions. If any step fails, the system rolls back automatically.
Rollouts proceed cell by cell, zone by zone, region by region, with automated monitoring comparing latency, error rates, and throughput between updated and non-updated clusters. Any statistically significant deviation triggers an automatic halt.
What made all of this possible is that EKS is built to operate without human intervention at the individual cluster level. Through Zero Operator Access, the architecture prevents AWS personnel from having technical pathways to access customer content in the managed control plane. A system designed to work without human access must be observable, recoverable, and automatable from the start, and that same discipline is what enables operating at extreme scale.
Three operational lessons shaped how we approach this work.
The first is that a healthy leader is not the same as a working one. The control plane’s controllers run in an active-passive configuration, and early on, we treated an unhealthy standby as if cluster operations had halted. They had not; what matters is whether a leader exists. But the harder lesson: a leader can quietly stop making progress while still renewing its lease and passing every health check. The signal that caught this was watching the controller’s work queue depth. If the queue fills while the leader looks healthy, the system is falling behind in ways no liveness probe will catch.
“A leader can quietly stop making progress while still renewing its lease and passing every health check. The signal that caught this was watching the controller’s work queue depth.”
The second is that maintenance ordering matters as much as the maintenance itself. etcd defragmentation is blocking, and the pause grows with database size. When it hit the leader, every write stalled. We taught the agent to move leadership to a healthy node before defragmenting, so the disruptive work always lands on a follower while writes keep flowing.
The third is that liveness is not readiness. A process can be alive but not ready while it warms caches, and routing based solely on liveness sends requests to an instance that cannot handle them. Equally, readiness flapping during graceful draining should never trigger a restart. We keep the two signals strictly separate: one decides recovery; the other decides routing.
None of this work is visible from the outside, and that is the point. The largest clusters taught us lessons that made every cluster faster. The riskiest migrations produced safety machinery that protects every upgrade. The upstream fixes we contributed for workloads at the edge of what Kubernetes can handle flow back to every user of the project.
“None of this work is visible from the outside, and that is the point.”
When you deploy on EKS and your pods come up in seconds, even during a burst, even when something behind the scenes goes wrong, that speed is not accidental. It is the accumulated result of years of operating at scales where small problems can become big ones fast, and engineering the system to contain them before they do.
Building with AI has, until recently, meant calling up someone else’s model. But wiring an app to an API from OpenAI, Anthropic, or Google is a poor fit for government and operators of critical infrastructure. When data legally or operationally cannot leave a secured network, a hosted endpoint in someone else’s cloud is a non-starter, regardless of whether the workload is intelligence analysis, grid operations, or patient records.
“The most revealing aspect here is that Palantir didn’t ship a model, but the apparatus for deploying and owning one.”
That’s the lens through which to read Palantir’s announcement on Monday. The company introduced an “intelligent engine,” built on Nvidia AI and Nemotron open models, for running, customizing, and continuously improving AI inside air-gapped and other sovereign environments while keeping data and model weights in the customer’s hands. The most revealing aspect here is that Palantir didn’t ship a model, but the apparatus for deploying and owning one.
From calling AI to operating it
Most organizations will run a hybrid of hosted and self-hosted models for years, but a second pattern is hardening alongside this workflow. Rather than treating the model as an external service, the application communicates with an internal AI platform that routes requests to one or more models running on the organization’s GPUs. Data never leaves the perimeter, which hands security and compliance teams direct control over governance, auditing, and retention.
So we’re seeing the question shift from which model we should call to which models we should own and operate ourselves. And, just as importantly, what does it cost us to run them?
What’s actually in the box
This is where the announcement gets more concrete than the press release lets on, and where it’s worth knowing what Nemotron is.
Nemotron is Nvidia’s family of open-weight models, released in 2026 in three sizes — Nano (~31.6B parameters), Super (120B), and Ultra (550B). All three use a hybrid Mamba-Transformer mixture-of-experts design that activates only about a tenth of their parameters per token, so they run far cheaper than their headline sizes suggest, with context windows up to a million tokens.
Nvidia publishes the weights, training data, and recipes under a permissive license, and the models are deployable via open runtimes such as vLLM, SGLang, and llama.cpp, Ollama — or as Nvidia NIM microservices, the containerized, TensorRT-LLM-optimized path that ships inside the Nvidia AI Enterprise suite. Palantir, notably, was already on Nvidia’s published list of early Nemotron adopters, so this is less a cold start than a formalization.
An important note for builders weighing the move: Nemotron doesn’t top the raw-capability leaderboards; open families like DeepSeek, Qwen, and Kimi K2 generally score higher on absolute benchmarks. Nemotron’s pitch is efficiency on Nvidia silicon and genuine openness, which is exactly the axis that matters when the deployment target is your own hardware behind an air gap rather than a hosted endpoint.
Palantir’s contribution is the layer that turns “download the weights” into “run this in a classified environment and keep improving it.” The company describes three engineering surfaces: deployment (getting base and customized models into air-gapped and classified networks), context (prompts, workflow structure, and model behavior in production), and model (changing the weights themselves on proprietary data and mission outcomes). Underneath sits Palantir’s existing stack — AIP, Ontology, Foundry, and Apollo — handling data authorization, enforced isolation, and auditability.
The “self-improving” claim is a telemetry loop: The engine captures usage and trace data, then uses it to post-train and align the model toward the tasks where it adds value. This is the part that demands the most operational discipline, because a feedback loop with no evaluation harness is a recipe to drift.
The catch: Owning the stack means owning the stack
The sovereignty pitch is genuinely attractive, and it has a price tag the announcement doesn’t dwell on. Owning your models means owning everything around them. That’s GPU capital expenditure and the power and cooling to match; an inference stack you keep patched and performant; a model lifecycle — fine-tuning, evaluation, rollback — that you staff and run yourself; and a security burden that doesn’t go away just because the box is disconnected.
“Owning your models means owning everything around them.”
Ultra-class models, in particular, are not modest: running a 550B model, even at ~10% activation, requires multi-GPU server nodes, not a spare rack.
For an agency that legally cannot use a hosted API, that cost is simply the cost of doing the work, and the calculus is easy. For a commercial enterprise that could use a hosted endpoint, the math is a real trade — control and data residency on one side, capex and operational headcount on the other. The right answer is workload-specific, and anyone selling it as obvious is selling something.
Read the announcement for what it is
It’s also worth being clear about what this news is not. It’s a packaging-and-positioning announcement between two companies with aligned incentives: NVIDIA sells more GPUs and more AI Enterprise licenses, Palantir sells more platform, and “sovereign AI” is the banner both have been marching under all year. There’s no named agency customer, no contract value, and no benchmarks. Palantir CEO Alex Karp says many U.S. clients already use these models and frames the appeal as avoiding proprietary insight being baked into the weights of closed models; NVIDIA’s Jensen Huang calls open source foundational to national security. Both quotes are doing strategic work. The substance here is the integration and the go-to-market, not a technical breakthrough.
Why it still matters
Strip away the government framing, and the same pattern is spreading through finance, healthcare, manufacturing — anywhere data residency and compliance are design constraints rather than afterthoughts. The reasons it’s newly practical are concrete: open models good enough for production, MoE architectures that cut the compute bill, and an inference tooling layer (NIM, TensorRT-LLM, vLLM) mature enough that air-gapped serving is an engineering project rather than a research one.
“The model becomes a component. The engine becomes the product.”
The takeaway here for developers is that as open models converge on “good enough,” differentiation shifts to everything around them — deployment, routing, governance, evaluation, security, and lifecycle management. The model becomes a component. The engine becomes the product.
Most organizations will keep calling hosted APIs for plenty of work. But for a growing set of them, the interesting question is how much of the stack they’re prepared to own — and whether they’ve counted the cost of owning it.
