Claude Opus 4.7 is Anthropic's flagship frontier model, released April 16, 2026 as a successor to Opus 4.6. It is Anthropic's strongest coding and agentic model to date, purpose-built for long-horizon autonomous work with minimal supervision. Opus 4.7 plans deliberately, writes verification steps (tests, runs, fixes) before declaring tasks complete, and uses file-system memory to carry context across sessions. New controls include task budgets and an xhigh effort level between high and max. At launch it topped SWE-bench Verified at 87.6% and SWE-bench Pro at 64.3%, ahead of GPT-5.4 and Gemini 3.1 Pro, with 69.4% on Terminal-bench 2.0 and ~77% on ARC-AGI-2. Vision capabilities tripled, enabling 98.5% computer-use visual acuity. It features a 1M-token context window and 128K output capacity.
