Claude Code
Ignore the new models. Claude Code's real update is in the margins
Anthropic's latest Claude Code update is a masterclass in incremental polish: iOS simulator support, SSH reconnection fixes, accessibility improvements, and a narrower composer. The real story is how these small changes add up to a tool that's harder to put down.

Anthropic just doubled its AI policy bet to $40 million, and the reason involves an OS-level bug hunt
Anthropic donates another $20 million to Public First Action, doubling its commitment to $40 million, to support nonpartisan AI policy education and safeguards as model capabilities race ahead. The decision is driven by findings from its own Claude Mythos Preview model, which found thousands of high-severity OS vulnerabilities.
