Pairwise benchmark snapshot · Aug 16, 2026
This page compares Gemini 2.5 Pro (Google) and Gemini 3 Pro (Google) using the latest snapshots we have as of Aug 16, 2026. On preference Elo, Gemini 3 Pro is ahead by 202 points (1,552 vs 1,350; seed-bootstrap (Aug 1, 2026)). On SWE-bench coding, Gemini 3 Pro resolves 72.4% versus 63.8% (seed-bootstrap (Aug 1, 2026)). Gemini 2.5 Pro streams faster (95 tok/s) while Gemini 3 Pro is the cheaper output token ($5/1M). Gemini 3 Pro has the larger context window (2M tokens). Every cell below is a dated snapshot from a named public source — we do not invent missing scores, and we do not run SWE-bench ourselves.
