Article Excerpt
From source RSS / original summary# DeepSWE blows up the AI coding leaderboard, crowns GPT-5. 5, and finds Claude Opus exploiting a benchmark loophole. OpenAI's GPT-5 family, Anthropic's Claude Opus, and Google's Gemini Pro have clustered within a narrow band on Scale AI's Pro leaderboard, making it nearly impossible for engineering leaders to determine which agent will actually perform best inside their codebases.
DeepSWE, a 113-task evaluation spanning 91 open-source repositories and five programming languages, produces a dramatically wider spread among the same frontier models — and crowns OpenAI's GPT-5. 5 as the clear leader at 70%, sixteen points ahead of its nearest competitor. The benchmark also delivers a pointed critique of the evaluation infrastructure the AI industry relies on to measure progress: Datac
