Gemini 3.5 Flash leads on more of the 5 benchmarks where both are measured — Gemini 3.5 Flash on 3, Muse Spark on 2. The remaining 4 of 9 tracked benchmarks cannot be compared: 3 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 5 of 9 tracked benchmarks for both models — Gemini 3.5 Flash leads on 3, Muse Spark 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

Muse Spark has no published result on Chess Puzzles, SWE-bench Verified, SimpleQA 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.
