Muse Spark 1.3 is the newest, released Sep 2, 2026. Gemini 3.7 Flash came out Aug 13, 2026; Gemini 3.6 Flash came out Jul 21, 2026. Knowledge cutoff: Gemini 3.7 Flash Mar 2026, Gemini 3.6 Flash Mar 2026.
How do you decide the winner?
Each model gets a 0–100 score on capability (50%, independent benchmark results); price (25%, blended price per million tokens (3 input : 1 output), log scale); inputs & features (15%, image, PDF, audio and video input, tool calling, structured output and reasoning); context window (10%, maximum tokens per request, log scale). Dimensions missing for any model are dropped and the remaining weights rescaled, so every model is judged on the same evidence. Specs and prices come from public model listings and the labs’ own API pages; capability scores come from independent benchmark runs. Data updated Oct 4, 2026.
