karminski3 spotted that Xiaomi is livestreaming its model training in real time, a rare public look at an ongoing training run, with several notable details:

Two models in post-training: mimo-v2.6-pro and flash are being trained in parallel, with the page labeled RL — indicating the post-training (reinforcement learning) stage.
It's Agentic RL: training progress is measured on the DeepSWE benchmark, but the run appears early-stage — mimo-v2.6-pro scores 62 on DeepSWE vs 74.2 for the leading DeepSeek-v4.1-flash.
The burn rate: roughly $10+ per second. Cross-referencing page metrics — stage 10 took 58 minutes and generated 2.2B tokens — lets viewers estimate token throughput and back out GPU count and likely time-to-completion.
