What happened
Xiaomi released and open-sourced the MiMo-V2.6 series — MiMo-V2.6-Pro and a smaller Flash variant — plus a Pro-UltraSpeed variant up to 20 times faster. Pro scored 46.32 on the Artificial Analysis Intelligence Index.
Why it matters
Xiaomi says Pro is the highest-ranked open-source/open-weight model in that comparison at launch, with 1 million-token context windows, and it claims Pro costs roughly one-20th to one-60th as much as overseas models at comparable intelligence.
What to watch
Pro still trails Claude Fable 5.1 and GPT-6 Astra on aggregate measures, and Xiaomi says the relevant business comparison is price per task, not price per token. Watch whether 20× faster generation justifies Pro-UltraSpeed's $4.35 and $8.70 pricing.
WHO IT HITSIt lands on teams evaluating cheaper open-weight alternatives for computer-use agents, coding and design agents, and document-heavy workflows, since the series is open-sourced and priced at MiMo-V2.5 API rates.

Xiaomi's move continues a pattern of open-weight releases aimed at agentic use cases. The company demonstrated the model on game worlds, Blender-based 3D modeling, embodied simulation and video-music workflows, and highlighted computer-use agents that read a task, a screenshot or video, reason, and decide the next step within one model loop.
On agentic tasks, V2.6-Pro's testing results were close to or occasionally above leading closed systems: 53.1 on AutomationBench versus Claude Opus 5's 50.3; 31.6 on Agents' Last Exam, tying Opus 5; and 89.9 on Terminal Bench 2.1, slightly ahead of Opus 5's 89.1. Yet the model still trails Claude Fable 5.1 and GPT-6 Astra on aggregate measures.
The pricing argument is Xiaomi's own: it claims Pro costs roughly one-20th to one-60th as much as overseas models at comparable intelligence, factoring in cached-token costs, versus $10 to $50 input and output per million tokens for GPT-6 Astra and Claude Fable 5.1. Whether that translates into lower cost per task is likely to hinge on reliability and how many loops a task takes to complete successfully.
