A closed-beta ultra-speed MiMo-V2.5-Pro API for very low-latency inference.
Xiaomi extended the UltraSpeed closed beta, but access remains limited to approved users and no fixed GA date is published.
ActionLatency-sensitive designs need a standard MiMo-V2.5-Pro fallback and should not depend on beta quota.
