GitHub published benchmark results for its Copilot agentic harness, which supports more than 20 models from providers including Anthropic, OpenAI, and others. The company claims the harness delivers leading token efficiency while maintaining flexibility across model choices.

A large-scale study testing 34,198 real-world skills reveals that AI agent performance drops drastically when moving from curated benchmarks to realistic conditions. Claude Opus 4.6 saw pass rates fall from 55.4% with hand-selected skills to 38.4% in truly realistic scenarios, while weaker models like Kimi K2.5 actually perform below their no-skill baseline.

GitHub has published technical details on the security architecture underlying its Agentic Workflows feature, which runs AI agents within GitHub Actions. The system implements process isolation, output constraints, and comprehensive audit logging to contain agent behavior.
