Claude Opus 4.6 - Claude’s most advanced model for agentic tasks
by•
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.

so smart and very accurate at fixing bugs
It has topped the tests again! What is its most distinctive feature that sets it apart from the others?

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.

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!
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.
The 1M context + agentic planning combo feels like a real step toward using models as long-term collaborators, not just responders. Excited to see how this changes complex code and research workflows.
Why is it actually slow? Is it the new tools or more reasoning? I was creating this

and it was actually terribly slow. So switched back to opus 4.5 but looks like they nerfed it?
Looking forward to using it in Claude Code!
Hi Team, congrats! What are the best use cases for financial teams you can see now?
