Too close to call
It is close. Our weighted score puts them within a point (Muse Glimmer 30B 57/100, Seed 2.1 Turbo 57/100, Motif 3 44/100), so choose by what matters most for your work: Muse Glimmer 30B on price and Motif 3 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.

Which is newer?
Muse Glimmer 30B is the newest, released Aug 10, 2026. Motif 3 came out Aug 7, 2026; Seed 2.1 Turbo came out Jun 23, 2026. Knowledge cutoff: Muse Glimmer 30B Jan 4, 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.
