Excited to share our most powerful new Claude Code feature: dynamic workflows!

Mention "workflow" in a prompt and Claude will dynamically create an orchestration plan that it strictly follows, allowing you to confidently trust that every stage happens in the right order even across 100s of agents.

We just shipped Opus 4.8! It's noticeably more honest, owning what it doesn't know and flagging problems in its own code instead of glossing over them. It's our recommended model for daily use in Claude Code.

This was SO fun to do. Working with @cognition has been one of the clear highlights of my last few years at Anthropic, and founders like @ScottWu46 are what make the job so cool

[Andrej Karpathy @karpathy]

Personal update: I've joined Anthropic. I think the next few years at the frontier of LLMs will be especially formative. I am very excited to join the team here and get back to R&D. I remain deeply passionate about education and plan to resume my work on it in time.

What does autonomous work even mean?

The biggest impediment for me has been the fact that I have to “crank” the model to continue in the direction that I want it to go.

With Opus 4.7 there’s less “cranking”

[Claude @claudeai]

Introducing Claude Opus 4.7, our most capable Opus model yet.

It handles long-running tasks with more rigor, follows instructions more precisely, and verifies its own outputs before reporting back.

You can hand off your hardest work with less supervision.

Bubble 🤝 Opus 4.7

@AnthropicAI brought us in before the release to test and send feedback, and we’re seeing a 5–10% improvement in cross-page visual consistency. Create an app with Bubble AI and you’ll notice the gains!

Excited for this one — everything you need to ship production agents at scale, without having to spend months on infra work.

More than a million people are now signing up for Claude every day.

To everyone choosing to make @claudeai part of how they work and think: welcome.

[Marius Buleandra @mariusbl]

Amazing to be part of this team, who has put so much effort into ensuring we’re on the right path!

I hope & believe anyone who understands the situation would support our position here. AI for mass surveillance or autonomous weapons is irresponsible at the very least; it’s puzzling why the DoW is so insistent on keeping these use cases on the table.

We just launched /remote-control so you can continue local Claude Code sessions from your phone

This is now rolled out to all Max users!

[Claude @claudeai]

New in Cowork: scheduled tasks.

Claude can now complete recurring tasks at specific times automatically: a morning brief, weekly spreadsheet updates, Friday team presentations.

[Lawrence Chen @lawrencecchen]

Introducing cmux: the open-source terminal built for coding agents.

- Vertical tabs
- Blue rings around panes that need attention
- Built-in browser
- Based on Ghostty

When Claude Code needs you, the pane glows blue and the sidebar tells you why.

No Electron/Tauri. Just Swift/Appkit.

This has one been one of my biggest productivity boosts of the past year. Highly recommend trying this out, in some ways it feels just as impactful as a model intelligence upgrade.
