GitHub Enterprise(@GitHubEnt):We benchmarked the GitHub Copilot agentic harness against the harnesses that ship leading models natively. Holding the model and task fixed across SWE-bench Verified, SWE-bench Pro, SkillsBench, TerminalBench, and Win-Hill, the results were clear: • Task resolution on par with model-vendor harnesses • Fewer tokens across most configurations A key learning: With GitHub Copilot supporting more than 20 models, you're free to pick efficiency or peak quality per task.
