Too close to call
It is close. Our weighted score puts them within a point (Nex-N2-Pro 57/100, Step 3.7 Flash 56/100, MAI-Code-1-Flash 41/100), so choose by what matters most for your work: Step 3.7 Flash on price and Nex-N2-Pro for long inputs. The score weighs inputs & features 60%, context window 40%. None of the shared benchmarks cover every model here yet, so capability is left out of this verdict.

MAI-Code-1-Flash is the newest, released Jun 2, 2026. Nex-N2-Pro came out Jun 2, 2026; Step 3.7 Flash came out May 29, 2026. Knowledge cutoff: MAI-Code-1-Flash Dec 2025, Step 3.7 Flash Mar 1, 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.
