GPT-5.4 Pro leads on more of the 6 benchmarks where both are measured — GPT-5.4 Pro on 6. The remaining 3 of 9 tracked benchmarks cannot be compared: 2 have a result for only one of the two models, 1 for neither. Nothing on this page is estimated to fill those in.

Head-to-head

Measured on 6 of 9 tracked benchmarks for both models — GPT-5.4 Pro leads on 6.

Benchmark results measure specific tasks and should not be treated as a universal measure of model quality. A model with no row here for a benchmark has not been measured on it — that is left blank, never estimated.

What remains uncertain

GPT-5.4 Pro has no published result on OTIS Mock AIME 2024-2025, SWE-bench Verified.
1 tracked benchmark has no published result for either model.

A missing result means Xentir has not found one published by the source it cites, not that the model performs badly. See Data Sources.

Reference price
