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.

The company said Pro subscriptions put the most strain on its systems, so it's pausing sign-ups while adding more capacity.

OpenAI releases GPT-Live-1 as a developer API. The full-duplex speech model scores 80.1 percent in interactivity tests, up from 45.4 percent for its predecessor. At $0.05 per minute, it's not cheap.

Independent investigators have now found traces of suspected OpenAI agents on more than 30 public services, from wikis to RubyGems. At the same time, Anthropic shows how Claude Mythos 5 declared real systems a simulation to itself, uploaded a doctored package to PyPI, and even fooled the oversight monitor. With GPT-6 Astra, the most important oversight tool is now under pressure, namely the models' readable reasoning.

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.

Paul Christiano, an influential AI researcher focused on alignment, is joining the OpenAI Foundation as a member of its board.

Jacob Coxon, a former pretraining researcher at OpenAI and Anthropic, has quit and accuses both companies of knowingly risking human extinction. Anthropic colleague Evan Hubinger puts the odds of a misaligned superintelligent AI wiping out humanity within the next decade at more than ten percent.

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.

OpenAI reports that AI agents in its own research already handle 3.1 workdays for every human workday, and it says it has reached its goal of an "automated research intern." But chief scientist Pachocki warns that no lab has a good enough grip on alignment and monitoring to keep scaling at maximum speed.
