When to pick which
The two are priced identically at $1.25/$10 per million tokens with the same 400K context window, so cost is a wash. GPT-5.1 is the newer revision with improved instruction following, better-calibrated reasoning effort, and generally stronger coding and agentic performance. For new builds there is no reason to pick GPT-5 over 5.1. Stay on GPT-5 only if you have evaluated pipelines pinned to it and want to avoid re-testing. Behavioural differences between revisions are small but real, especially around tool-call formatting and refusal boundaries.
