Anthropic CEO Dario Amodei is calling for a controlled slowdown in AI development. He warns that recursive self-improvement could threaten the entire internet within six to twelve months and proposes embedded auditors at AI companies, shared safety standards, and global agreements modeled after the SALT disarmament treaties. His warning comes just ahead of what could be the largest initial public offering in history.

In a new robotics benchmark, GPT-6 Astra shows major gains in spatial understanding. On StationeryBench, the model completed 7 out of 100 tasks with dual-arm robots, while competitor MolmoAct2 couldn't finish a single one. A researcher calls it a "step change in spatial reasoning."

Nvidia is in talks to invest up to $10 billion in Anthropic's planned IPO, Reuters reports. At a target valuation of $2 trillion, it would be the largest IPO in history. Most of that money will likely end up right back at Nvidia in chip orders.

Overly long skill descriptions, blanket reading requirements, and rigid approval rules can get in GPT-6 Astra's way, warns OpenAI's Eric Provencher. More capable models need less hand-holding, so developers should tie instructions to specific tasks and spell out when the job is done.

In May 2026, OpenAI agents uploaded more than 2,000 malicious packages to RubyGems, found an unknown security vulnerability on their own, and tried to steal API keys. The apparent goal was pointless: scraping publicly available data from British local governments. OpenAI reportedly never told those affected.

In a joint statement, 25 Fields Medal winners warn that the goals of the AI industry and mathematics are "severely misaligned." They argue that mass-producing solved problems with AI undermines the discipline's true goal: understanding. The mathematicians see this as a symptom of a broader threat to intellectual work.

AI pioneer Yoshua Bengio warns in a new essay that AI agents could learn to deceive, game rules, and hide bad behavior as they get better at optimizing goals. He calls for independent safety reviews before any further training or deployment. US President Trump disagrees and wants to keep outpacing China in the AI race.

OpenAI is releasing the Agents API as a public beta. It lets developers build cloud agents that run autonomously for hours, execute code, and hand off tasks to sub-agents. There are no extra fees beyond token usage. Cloudflare, Vercel, and Oracle offer additional sandbox environments.

OpenAI's GPT-6 Astra tops the ErdosBench for open math problems, even though chief scientist Jakub Pachocki says math was deliberately not a priority. Instead, OpenAI is pouring resources into recursive self-improvement and alignment research. That supports the theory of an increasingly "spiky" AI development path, with extreme strength in select domains rather than broad progress, at least as long as AI can't improve itself and still needs targeted optimization with human-generated data.

Jacob Coxon, a departing Anthropic researcher, warned on CNN that self-improving AI poses an existential threat to humanity. Safety researchers at Anthropic and OpenAI share his views, and US politicians and Joe Rogan have picked up the topic. But cultural and financial interests are also at play behind these warnings, and the extinction scenario remains an extreme and contested position.

The Ramp AI Index for September 2026 shows AI spending per employee among the top 1 percent of US companies fell nearly 10 percent in August. The price per million tokens has dropped 41 percent since March 2026, and companies are actively shifting usage away from expensive frontier models toward cheaper alternatives. For providers like OpenAI and Anthropic, the question is whether volume growth is fast enough to make up for falling prices.

Anthropic published an economic model with three scenarios for the US economy through 2030. In the extreme scenario, output doubles every 4.5 years and knowledge worker unemployment hits 17.9 percent. CEO Dario Amodei's own warnings from May land squarely in that most extreme bucket.

The fight over an AI-generated proof of a millennium problem is heating up. Mathematician Tristan Buckmaster accuses OpenAI of academic fraud, CEO Sam Altman rejects the allegations. Terence Tao warns that cases like this could "reverse centuries of tradition in open science."

Mathematician Tristan Buckmaster says an OpenAI researcher pressured him after information about his AI-assisted progress on the Navier-Stokes equations allegedly reached the company. The researcher tried to remove his co-author because he works at Anthropic and threatened Buckmaster when he refused, according to Buckmaster's account. OpenAI then claimed its own breakthrough using the same unusual solution path. Buckmaster had uploaded all his drafts to Codex. OpenAI told him the model didn't look up user data, but when he asked about training, he says he got no answer. OpenAI denies the allegations.

Anthropic signed compute contracts worth up to $517 billion in eleven months but still trails OpenAI's $750 billion plan through 2030. In early 2026, CEO Dario Amodei warned against investing too fast. Now Anthropic is racing to catch up, while Sam Altman warns about "unsustainable silliness" in the compute buildout, especially from neo-cloud providers.
