Per token is not per task: an average task of Artificial Analysis' Intelligence Index cost $7.77 on Gemini 3.8 Flash (high) and $0.257 on MiMo-V2.6-Pro, and MiMo-V2.6-Pro wrote 1.2× as many output tokens for the same work.

Each model is compared at its best-ranked reasoning-effort setting. Gemini 3.8 Flash (high) scores 61.8 and takes 18 s to its first answer token; Gemini 3.8 Flash (medium) scores 60.3 in 11 s, Gemini 3.8 Flash (low) scores 55.9 in 4 s. MiMo-V2.6-Pro scores 57.1 and takes 26 s to its first answer token. Higher effort means more thinking before the answer: better scores, longer waits and more tokens billed.
