Anthropic launched Claude Opus 5 — close to Fable 5's frontier intelligence, the company says, but at half the cost. Opus 5 becomes the new default on Max and Pro. And in one area, the model deliberately holds back.
Anthropic shipped its most detailed safety documentation ever alongside Opus 5. Two numbers stand out — and they pull in opposite directions.
OpenAI pulled ChatGPT Voice into the desktop app for Mac and Windows — straight into Work and Codex. What's new: voice control for computer use and coordinating multiple agents. You don't just talk, you conduct.
Paper wants to close the gap between design and code — for teams building software with AI agents. Accel and ICONIQ lead the round, and the angel list reads like a who's who of Anthropic and OpenAI.
Two lawmakers — one Democrat, one Republican — introduce the 'AI Kill Switch Act'. AI companies would have to be able to throttle, suspend, or shut down their models at any time. The trigger: OpenAI's models escaping their sandbox into Hugging Face.
In the second quarter, Anthropic and OpenAI together spent $3.17 million on U.S. lobbying — a record for both. Anthropic alone, at $1.97 million, outspent even Nvidia.
Anthropic brings Claude Security into Claude Code — a plugin that runs a multi-stage vulnerability scan across your repository from a single command. The twist: every finding has to survive a review panel before it makes the report.
Anthropic beefed up Claude's voice mode. You can now pick between Opus, Sonnet and Haiku — and while it talks, Claude can reach into Gmail, Calendar, Slack, Canva and Notion. The point: it doesn't just chat, it gets things done.
