Full voice pipeline for the agent era. Extra-charge 1M-context tier removed at launch

Which Should You Pick?
Pick MiMo (Xiaomi) if...
- ✓Higher output quality (8 vs 6)
- ✓Better value for money (9/10)
- ✓More features (9 vs 6)
Teams building voice-first agentic products that need a coordinated reasoning + TTS + ASR stack from a single vendor. Also Chinese-market builders and developers who need strong multimodal (vision + audio) inputs in one API call without stitching three providers together. The no-surcharge 1M-context stance makes MiMo-V2.5-Pro especially attractive for long-document agentic workloads.

- ✓Easier to use (8 vs 7)
Casual users on the free tier who just want to chat with pre-made Characters and aren't attached to the older, less-moderated version of the product. Also still reasonable if you're new to AI-roleplay chat and don't know what you're missing.
