Xiaomi Streams MiMo‑V2.6 Reinforcement Learning Training Ahead of Imminent Release

The run tests whether large‑scale, multi‑agent evaluation‑driven RL can push model capabilities while Xiaomi says it will publish training details in the coming weeks.

Overview

  • Xiaomi’s MiMo‑V2.6 is in an intermediate reinforcement learning training phase and the team is publicly streaming the run with the livestream page signaling an imminent release.
  • The team expanded core infrastructure to support larger RL workloads, reporting roughly 2 billion tokens per training step in a fully asynchronous setup with 1,568 prompts and 16 rollouts.
  • MiMo‑V2.6 adds broader environment and tooling to run multi‑task and agentic RL experiments and includes a dedicated “Grader Compute” cluster that allocates extra compute to scoring and reward assignment.
  • Xiaomi reported cumulative training spending has passed $1.25 million, which the report notes is about ¥8.4 million at current exchange rates.
  • The company says it will gradually open‑source the RL training details and materials over the next few weeks, a move that could let outside researchers inspect the team’s techniques and reproduce the experiments; Xiaomi previously open‑sourced MiMo‑v2.5 in April 2026.
