Too close to call
It is close. Our weighted score puts them within 1 points (Nemotron Nano 9B v2 64/100, Mistral Nemotron 62/100, Apertus 8B 56/100), so choose by what matters most for your work: Mistral Nemotron on price and Nemotron Nano 9B v2 for long inputs. The score weighs price 50%, inputs & features 30%, context window 20%. None of the shared benchmarks cover every model here yet, so capability is left out of this verdict.

Apertus 8B is the newest, released Sep 2, 2025. Nemotron Nano 9B v2 came out Aug 18, 2025; Mistral Nemotron came out Jun 11, 2025. Knowledge cutoff: Apertus 8B Sep 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 Oct 4, 2026.
