Claude Opus 4.7
Claude’s most capable model for reasoning and agentic coding
Visit website →About
Claude Opus 4.7 is a model in Anthropic's Opus line, built for complex reasoning and agentic coding. It is designed to handle long-running tasks without losing the thread, follow instructions precisely, and verify its own outputs before presenting them.
It targets demanding work across coding, research, and multi-step workflows, where an agent has to plan, use tools, and stay coherent over an extended session rather than answer a single question.
It is aimed at developers and businesses building agents, coding tools, and analysis systems that need a high-capability model for the hardest parts of a workload, available through Anthropic's API and apps.

Why we picked it
Opus 4.7 made the cut for verifying its own outputs before presenting them — self-checking on long-running tasks matters more than raw benchmark gains for anyone who's had an agent confidently hand back something subtly wrong after a multi-hour run.
