Head to head · OpenRouter
Xiaomi MiMo-V2.6-Pro vs Xiaomi MiMo-V2.6-Pro-UltraSpeed
The catalogue describes both as the same 1T MiMo-V2.6-Pro checkpoint and says UltraSpeed matches Pro's quality. UltraSpeed costs exactly 10x more: $4.35 in / $8.70 out per million against $0.435 / $0.87.
Quick verdict
This is a speed purchase, and the catalogue does not publish the speed number — no latency or throughput figure appears for either entry. Buy UltraSpeed only after measuring it against Pro on your own path; otherwise the 10x is a premium paid on faith, and at $8.70 per million output tokens it is the most expensive entry in the snapshot.
