GitHub Changelog·medium signal

GitHub began rolling out Claude Opus 4.7 on Copilot on April 16, the same day as Anthropic's launch. GitHub's early testing shows stronger multi-step task performance and more reliable agentic execution versus Opus 4.6, with meaningful improvement in long-horizon reasoning and tool-dependent workflows. CodeRabbit's code review testing found Opus 4.7 is 'the sharpest model tested' with recall improved by over 10%, catching difficult-to-detect bugs that other models miss. For builders running Copilot: model swap is automatic, no configuration change needed.
