Voxtral Small 24B 2507 is the newest, released Jul 15, 2025. Reka Flash 3 came out Mar 10, 2025; Phi-4-mini came out Feb 26, 2025. Knowledge cutoff: Phi-4-mini Jun 2024, Reka Flash 3 Jan 31, 2025.
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 Nov 2, 2026.
