Which should you choose?
Which is better: Morph V3 Large or Morph V3 Fast?
It is close. Our weighted score puts them within 2 points (Morph V3 Fast 32/100, Morph V3 Large 30/100), so choose by what matters most for your work: Morph V3 Fast on price. 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 cheaper, Morph V3 Large or Morph V3 Fast?
Morph V3 Fast is cheaper at $0.80 input / $1.20 output per million tokens (median across 5 API providers). Morph V3 Large costs $0.90 input / $1.90 output per million tokens (median across 5 API providers).

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.
