Felo Search Blog·high signal

Over 51% of all code committed to GitHub's platform in early 2026 was either generated or substantially assisted by AI code generators, crossing the majority threshold for the first time. In professional settings, Claude Code has risen to share second place alongside GitHub Copilot at 18% each. 90% of professional developers now use at least one AI tool regularly at work. Claude Code leads on SWE-bench Verified at 80.8% for complex debugging and large-codebase work. This data point marks the inflection where AI-assisted code becomes the default rather than the exception in professional software development.
