Claude Opus 4.6 is Claude’s most capable model yet, built for deep reasoning, long-running agentic tasks, and large codebases. With a 1M token context window, adaptive thinking, and improved planning, it delivers state-of-the-art performance across coding, analysis, research, and real-world work.
Hey everyone 👋
Sharing Claude Opus 4.6, Claude’s newest and most capable model. Built for large codebases, long-running agent workflows, and deep reasoning. It handles huge context, plans before acting, and stays reliable over time.
Would love your thoughts.
Helped me debug a problem I've been stuck for three days in just 15 mins ahhhh! It then explained everything that went wrong too. Super cool and helpful imo.
I used it yesterday, The speed and how it reasons is another level I felt. Also the agent team capability is so powerful that I cannot actually put it in words. I used it to make a model on top of my declarative language for cyber risk.
Been building with Claude's streaming API (SSE on Edge Runtime) for the past few weeks. The jump from Sonnet to Opus for agentic tasks is noticeable — especially the planning and reasoning over large codebases. The 1M token context window is a game changer for working with full project contexts. Excited to see where agent teams go.
Congratulations on the launch. Pushing reasoning depth, long context, and real agentic capability in one model signals clear progress toward AI that can handle meaningful work end to end.
The ability to manage large codebases, extended research, and complex planning within a single flow changes how developers and teams approach problem solving. This feels less like an incremental update and more like a shift toward dependable execution.
Claude Opus 4.6 looks carefully designed for real world impact where consistency, scale, and thoughtful intelligence truly matter.
Nice! We already integrated Opus 4.6 in https://brew.new/ and it's working extremely well. Keep it up!
I feel like this is the first time my AI assistant has a really sharp and witty sense of humor and I love it. Opus 4.6 might be my new favorite.
I really love that Claude is focusing on thinking more instead of a speed. I am using Claude Code constantly now, and FEEL how it gets smarter, 4.6 is top of the top. Thank you so much guys for making my project be faster than ever ❤️
The launch frequency is getting out of hand - building faster than we can even look at the products haha! Will poke around later today but congrats on the rollout
Agent Teams sound incredible! How do you manage token costs when the lead agent synthesizes results from multiple sub-agents? Seems like coordination overhead could add up fast.
Excited to try this!
1M context + actually plans before acting is the hook for me. My monorepo’s a tangle and agents drift by hour 2. If this keeps focus and finishes, not just chatters, that’s huge. I’ll throw it a week‑long cleanup and see if it stays on the rails.
It has topped the tests again! What is its most distinctive feature that sets it apart from the others?
So excited to be integrating it on Krater, a lot of our users were looking forward to it!
Hi Team, congrats! What are the best use cases for financial teams you can see now?
