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.

Claude Opus 4.6 is Anthropic's most intelligent model released in February 2026, built for agents that operate across entire workflows rather than single prompts. It features a 1M-token context window, 128K max output tokens, and the ability to spawn and coordinate multiple sub-agents working in parallel — a capability called Agent Teams. With adaptive thinking that dynamically adjusts reasoning depth, the model excels at large codebases, complex refactors, sustained knowledge work, and end-to-end project execution, producing near-production-ready documents and analyses in a single pass.
