❯ Xiaomi releases open-weight MiMo-V2.6 Pro and Flash; an independent index ranks Pro first among open models

ReleaseXiaomi released the MiMo-V2.6 Pro and Flash weights alongside a technical report and reinforcement-learning research resources. The company says the models can take text, image and audio inputs and are available on its platform at unchanged API prices.

Benchmark scopeArtificial Analysis assigned Pro an Intelligence Index score of 46, the highest among open-weight models it tracks, and estimated a cost of about $0.13 per index task. That supports a lead on this index, not a claim of superiority on every task. Xiaomi’s comparison with Claude Opus 5 and GPT-5.6 Sol depends on particular agent benchmarks and setups.

Deployment choiceWith both Pro and Flash available, developers can compare capability against the resources needed to run them. Application companies gain another model they can download, adapt and host instead of judging only closed-API prices. Reliability, serving expense and performance on actual workloads will determine adoption.

▪ SIGNALOpen weights are now competing on task-level cost at frontier-like performance, not merely on whether they can approach the frontier.
