Anthropic on Thursday launched the latest version of Opus, which now plans more carefully, sustains agentic tasks for longer, can operate more reliably in larger codebases, and has better code review and debugging skills to catch its own mistakes.
The company, in a blog post, said that Opus 4.6 can apply its improved abilities to a range of everyday work tasks: Running financial analyses, doing research, and using and creating documents, spreadsheets, and presentations. Within Cowork, where Claude can multitask autonomously, Opus 4.6 can put all these skills to work on your behalf.
"Opus 4.6 often thinks more deeply and more carefully revisits its reasoning before settling on an answer. This produces better results on harder problems, but can add cost and latency on simpler ones.
"If you’re finding that the model is overthinking on a given task, we recommend dialing effort down from its default setting (high) to medium. Opus 4.6 is much better at retrieving relevant information from large sets of documents. This extends to long-context tasks, where it holds and tracks information over hundreds of thousands of tokens with less drift, and picks up buried details that even Opus 4.5 would miss," said Anthropic.
Opus 4.6 availability
The company stated: "Claude Opus 4.6 is available today on claude.ai, our API, and all major cloud platforms. If you’re a developer, use claude-opus-4-6 via the Claude API. Pricing remains the same at $5/$25 per million tokens; for full details, see our pricing page."
