Neither model leads on more of the 4 benchmarks where both are measured — Gemma 3 27B on 2, GPT-4.1 nano on 2. The remaining 5 of 9 tracked benchmarks cannot be compared: 3 have a result for only one of the two models, 2 for neither. Nothing on this page is estimated to fill those in.

Head-to-head

Measured on 4 of 9 tracked benchmarks for both models — Gemma 3 27B leads on 2, GPT-4.1 nano leads on 2.

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-4.1 nano has no published result on Chess Puzzles.
Gemma 3 27B has no published result on FrontierMath, SimpleQA Verified.
2 tracked benchmarks have 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.
