Mid-tier on SWE-bench Verified, well below the open-agent leaders. The leaderboard ranks Aider in architect mode on Claude Sonnet 4.5 at 31.4% Verified and 24.0% Full, against OpenHands with CodeAct v3 at 68.4% and Cline at 59.8%. The figure comes from an aggregator leaderboard (awesomeagents.ai) rather than a primary SWE-bench publication, which is why confidence stays medium.
