Claude Cowork comes to every conversation, plus 1 more change

We're rolling out a new Claude experience that makes everything Claude Cowork does available from any conversation. Ask a quick question or hand Claude a bigger task, like a report, spreadsheet, or presentation, without choosing a mode first. Your chats, Cowork tasks, projects, connectors, and skills carry over. The new experience is rolling out gradually to Pro and Max plans on web, desktop, and mobile. Learn more in Claude Cowork and chat are one Claude. You can now ask for a design, deck, or document in any conversation with Claude, including in Claude Code and the Artifacts tab, and edit it with Claude or directly as you work. Claude Design works inside your conversations with all of its features, including on-canvas editing and importing your design system. Claude Slides gives presentations their own starting point, and Claude Docs is a new way to write living documents with Claude and your team. Artifacts, including Claude Design, Claude Slides, and Claude Docs, are available on every plan, including Free. On Enterprise plans, Claude Design, Claude Slides, and Claude Docs are in beta and off by default until an owner turns them on. Learn more in What are artifacts and how do I use them? and Get started with Claude Docs.

The Messages API can now compact a conversation on demand on the Claude API, in beta with the…

Send the top-level compaction parameter, and the API returns a signed compaction block that summarizes the messages you sent. On later requests, send that block first, in place of those messages. You choose when to compact, the request can run in the background, and you can keep recent turns word for word after the summary. On models with preserved thinking, the thinking in those kept turns can stay valid. With the thinking-binding-controls-2026-08-01 beta header, the input_transformations response field gains a second entry type, thinking_mismatch_allowed.
