Classic MiMo architecture with huge RL batches: 1568 tasks x 16 rollouts per step, surprising results
stochasticchasm · x · 2026-09-22
The author notes MiMo uses a classic architecture — simple yet strong. The RL run used an enormous batch size at every step: 1568 tasks with 16 rollouts each, meaning the run consumed a lot of tokens. Even so, the results remain surprisingly good.
