Claude Opus 4.7
Anthropic·Mar 2026reasoningproprietary
Claude Opus 4.7 was the incremental Opus release between 4.6 and 4.8, sharpening agentic coding (82% SWE-bench Verified) and long-context reliability. Opus 4.8 has since superseded it with the same pricing and a cheaper Fast Mode, so new projects should generally start on 4.8 — but 4.7 remains available for teams that pin model versions for reproducibility.
