Published benchmark scores
Benchmark scores for OpenAI: GPT-5.5 — every row links to its source, and a score is only ever attached to the exact checkpoint it was measured on. Vendor model-card and open-leaderboard numbers are cited, not run by us. Rows marked TrustedRouter · replays published are our own runs of this model through the gateway, with the full per-item replay published in trustedrouter-benchmarks so anyone can re-grade them.
