GPT-6 Astra costs $10.00 per million input tokens and $50.00 per million output tokens; MiMo V2.6 Flash RL costs $0.14 and $0.28. That makes MiMo V2.6 Flash RL about 99% cheaper for the same work.
How do you compare the two?
We use the 22 benchmark tests both models have published scores on. The verdict counts the 12 tests in the eight capability areas, and a gap under one point (ten on rating-style scales) counts as a tie. The other 10 are listed but not counted, because several are summary scores or repeat a test. Each score is the one shown on the model's own page.
