Pairwise benchmark snapshot · Aug 16, 2026noindex (thin pair)
This page compares Google: Gemini 3.1 Flash Lite (Google) and GLM-5.3 (Zhipu) using the latest snapshots we have as of Aug 16, 2026. Google: Gemini 3.1 Flash Lite wins on output price at $1.5/1M. Google: Gemini 3.1 Flash Lite has the larger context window (1M 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.
