Cloud sessions run on Anthropic-hosted infrastructure, so the work keeps going even without your computer running. Start one at https://t.co/scIJefCE5h, from the Code tab in the Claude mobile app, from the desktop app, or with claude --cloud in the CLI. 256K views · 527 likes · 11 reposts · 15 replies Open on X →

Cloud sessions are officially available and out of research preview! They let you keep Claude Code working, even when your laptop is closed. Existing subscribers get a one-time credit to try them: $100 on Pro, $250 on Max. https://t.co/SvdB2ATkFw

As our models grow more powerful, safeguards are one way we prevent misuse. Opus 5.5 is the first Opus with Fable 5.1-class safeguards on cyber, bio, and frontier LLM development. Flagged requests fall back to another model, and we're working to reduce incorrect flags. 50.7K views · 282 likes · 6 reposts · 18 replies Open on X →

Thinking is always on for Opus 5.5. Medium is the default, and you can adjust `effort`. For long-running agents, compaction summarizes older turns while keeping recent ones intact: https://t.co/y8E1Z9HdA6. And if you need more speed, fast mode goes up to 2.5x ($8/$40). 74.2K views · 271 likes · 3 reposts · 3 replies Open on X →

On the Claude Platform, Opus 5.5 is $4/$20 per million tokens, down from $5/$25. Cache reads drop 60%, from $0.50 to $0.20. Run `/claude-api migrate` in Claude Code to switch to `claude-opus-5-5`.

If you're on Pro, Max, or Team, your reset is available today in Settings → Usage. Apply it any time until Oct 22. Opus 5.5 is the default for paid plans.

Opus 5.5 is a lot better at writing too. It’s clearer, uses less jargon, and follows the writing rules you give it. Long Claude Code sessions are much easier to follow! 79.6K views · 953 likes · 16 reposts · 18 replies Open on X →

Today we're rolling out Projects in Claude Code on desktop and web. A project is one conversation with Claude. It splits the work into threads itself, runs them as parallel cloud sessions, passes context between them, and keeps going when you leave. In beta for select users. ht

Claude Design, Claude Slides and Claude Docs also work inside Claude Code now. Ask for a design review deck or a UI mockup and point it at the actual files and RFCs in the repo. Edit it yourself or keep going in the conversation, and share the link when it's ready. 638.6K views · 5.3K likes · 367 reposts · 158 replies Open on X →

Evals call the model, so they use tokens and results vary. Pilot with `--runs 1` before a full run. Your plugin's hooks and MCP servers run as you, so only evaluate plugins you trust. Run claude update to try it. Docs: https://t.co/K3fKEzO7bI 34.7K views · 98 likes · 5 reposts · 2 replies Open on X →

Then run `claude plugin eval` You'll see each case's score with and without your plugin in your terminal, plus an HTML report with the full detail. If your account supports it, the report is also published as a private artifact. 39.6K views · 88 likes · 1 reposts · 3 replies Open on X →

Start in your plugin's folder and run `claude plugin eval init` You tell Claude what good and bad output looks like and bring a few real prompts. Claude drafts the test cases and checks, pilots the suite, and tells you what a full run will cost. 35.8K views · 146 likes · 5 reposts · 3 replies Open on X →

Two fresh updates to Claude Managed Agents: First, we've added a session viewer to the ant CLI. `ant beta:sessions connect` attaches your terminal to a running session, and `--web` opens a web UI served from localhost. https://t.co/1UgRRLyxUA

You can pop out any pane in the Claude Code desktop app into its own window. Drag the diff or terminal to a second screen while Claude keeps working in the main window, then dock it back whenever you want. You can also run sessions side-by-side or stacked. https://t.co/5BF38zm4k
