Claude Cowork and chat are now one Claude

Anthropic is merging Claude Cowork and Claude chat into a single general-purpose agent experience, rolling out first to Pro and Max plans.

Simon Willison reports that Claude Cowork and Claude chat are merging into one Claude interface starting today, letting users hand off quick questions or longer tasks that continue running even after the laptop is closed. The rollout covers the Claude app on web, desktop, and mobile over the coming weeks for Pro and Max subscribers. Willison notes this effectively turns Claude into a general agent in its own right.

Claude's new system prompt really doesn't want to reproduce song lyrics

Anthropic published updated Claude consumer system prompts, including changes steering the model away from reproducing song lyrics, likely over copyright concerns.

Anthropic publishes system prompts for Claude.ai and Claude mobile apps, including historic revisions, and has reorganized them into an index with per-model pages such as the Haiku 4.5 page showing the original October 15, 2025 prompt and an updated January 18, 2026 version. The latest consumer prompt strongly discourages reproducing song lyrics, a behavioral constraint likely tied to copyright considerations. Prompts for Claude Cowork and Claude Code are not included in the published set.
