Serena Ge (Datacurve) released DeepSWE on 2026-05-28 as a new benchmark standard for agentic coding. DeepSWE aims to expose practical differences between leading models (notably referenced with Codex and GPT-5.5) by evaluating behaviors and failures developers encounter in day-to-day coding, rather than relying on narrowly similar public leaderboard scores.

Today we’re releasing DeepSWE, a new standard for agentic coding benchmarks.
On public leaderboards, top models often look relatively close in capability. DeepSWE shows where they actually diverge, reflecting the realistic experience of developers in their day-to-day work.
