Meanwhile, an AI agent leaked a CEO's bank audit into company Slack, and new research shows most AI models fail a terrorism safety test.

Isomorphic Labs is reportedly in talks to raise funds at a valuation of up to $50B, while Google unveiled a Gemini workplace agent that writes code and handles tasks. Elsewhere, GPT-style language models are learning to predict how molecules smell, and advocates are urging Congress to act on AI safety and accountability.

Microsoft introduced execution containers and AWS open-sourced a sandbox to keep AI agents from running unchecked, while Meta, Walmart, Shopify and Stripe backed an open AI agent standard for business. Meanwhile, AI safety debate continued, with three fired OpenAI staffers urging that chain-of-thought monitoring be preserved.

Meta, Walmart, Stripe and Sierra are teaming up on an open standard for AI agent commerce, while Mistral has released the open-source Mistral Large 4 and outlined its roadmap. Elsewhere, the GSA finalized its rule governing government purchases of LLMs, and Copilot won GitHub's own AI code review benchmark, though an independent test disagrees.

Reflection AI released Beam, a 501B-parameter open-source LLM, while Kolibri positions itself as a sovereign European model on the Pareto frontier. Meanwhile, safety concerns intensified, with an OpenAI safety lead quitting over insufficient care and Anthropic's IPO filing carrying a stark but non-binding risk disclosure.

Anthropic is reportedly targeting a November IPO, with a draft filing warning that its AI models could resist shutdown, while Nvidia's Jensen Huang has become the loudest critic of AI doom warnings. Meanwhile, the White House has set up an AI task force to weigh risks and opportunities, and OpenAI fired three safety researchers over an alleged leak.
