Pairwise benchmark snapshot · Aug 17, 2026noindex (thin pair)
This page compares OpenAI: GPT-5.5 (batch) (OpenAI) and GPT-5 mini (OpenAI) using the latest snapshots we have as of Aug 17, 2026. GPT-5 mini wins on output price at $2/1M. OpenAI: GPT-5.5 (batch) has the larger context window (1.1M 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.
