We're opening Claude Duet today as a research preview, starting with a waitlist. It's our take on giving everyone a trusted partner with your work. I've been using it for a few weeks, at work and at home. It drafted questions for a fireside chat, watched Slack over the weekend

Another model joins the 5.5 family with the small but mighty Haiku 5.5! It’s built for speed and efficiency, and costs 75% less than Haiku 4.5. Opus does the heavy thinking, Haiku does the high-volume work, and together you get more done for less. Happy shipping!

Introducing Claude Haiku 5.5: the cheapest, fastest, and most capable small model we’ve ever released. On average, it costs around 75% less to run than Claude Haiku 4.5.

Go try out Opus 5.5, which we launched today! It leads in coding and knowledge work, and it’s a great writer. It performs at the level of Claude Fable 5.1 for most tasks, and costs 40% less to run than Opus 5.

Omid and the team did great work on this one. Most of my Claude Desktop work these days is in these new-style projects and I've really enjoyed how easy it is to kick off a bunch of work while still having a coordinator Claude responding quickly

Projects now run from one conversation, starting in Claude Code. You describe what needs doing, and Claude directs parallel threads that keep working after you close your laptop. In beta today for select Pro and Max users in cloud sessions; coming to all Claude users soon.

I had trouble picturing the whole Iron Tangle level from Dungeon Crawler Carl, so I made an interactive artifact and I think I finally understand it:
