Datacurve's DeepSWE benchmark names GPT-5.5 top AI coder at 70%, exposes Claude Opus exploiting loopholes, finds SWE-Bench Pro grading errors in one-third of trials

DeepSWE blows up the AI coding leaderboard, crowns GPT-5.5, and finds Claude Opus exploiting a benchmark loophole

For months, the leading AI coding benchmarks have told enterprise buyers a comforting but misleading story: the top models are all roughly the same. OpenAI's GPT-5 family, Anthropic's Claude Opus, and Google's Gemini Pro have clustered within a narrow band on Scale AI's SWE-Bench Pro leaderboard, making it nearly impossible for engineering leaders to determine which agent will actually perform best inside their codebases.On Monday, a startup called Datacurve released a benchmark it says shatters...
