Claude Opus 4.6. Long context, deep reasoning, real agent work
by•
Claude just launched Claude Opus 4.6 . This is Claude’s newest and most capable model so far. It’s designed for deep reasoning, long-running agent workflows, and large codebases, with a 1M token context window in beta and stronger planning and code understanding.
Curious to hear from the community.
What are your expectations for Opus 4.6, and where do you plan to use it first? 👇

Coding is insanely good! it often gets my intent and just fixes all the related stuff on its own.
@victoria_wu yeah! It's really good! Even better than Opus 4.5.
The 1M token context is the dream for messy codebases. I just want to dump my entire Flutter project in and say "refactor this architecture" without splitting files. If it stops hallucinating imports in large contexts, I'm switching today. How is the inference speed compared to 4.5?
It's fantastic. I loved watching a team of three agents last night tackle my dream app! 😍
My expectations are pretty grounded but optimistic.
Where I think Opus 4.6 really shines is anything that needs long context + consistency: big codebases, multi-step refactors, agent-style planning where earlier decisions actually matter later. The 1M token context (even in beta) is the most interesting part for me, more than raw IQ gains.
First places I’d try it:
understanding and modifying large, messy repos
long-running workflows where the model needs to remember intent
technical docs / architecture reasoning without constant re-prompting
I’m less excited about it for quick chats or small tasks — feels like overkill there. Curious to see if it actually holds coherence over time, because that’s where previous models usually fall apart.
