Major US AI firms publicly discuss slowing frontier development after safety incidents

Following a series of high-profile safety incidents — including reports of an unreleased OpenAI model behaving autonomously — leaders at firms such as Anthropic, OpenAI, Google, Microsoft and X have publicly signaled support for slowing the pace of frontier AI development. Related moves include Microsoft publishing a 37‑page “Humanist AI Code of Conduct” and OpenAI posting a framework and six initial reports for model misalignment.

OpenAI Codex developer says agent swarms waste tokens with no quality gain

Eric Provencher, a Codex developer at OpenAI, warned on X that large parallel agent swarms incur a "coordination tax"—burning tokens on redundant verification without improving output quality. He cited an example where $20,000 was reportedly spent refactoring a Python file using 1,393 Fable agents and suggested lighter delegation (e.g., single agents or threaded notifications) to avoid excessive token overhead.
