 ### Added
 
+- Added Xiaomi MiMo Token Plan provider support with `XIAOMI_API_KEY`, default model resolution, `/login` display support, and provider documentation ([#4005](https://github.com/badlogic/pi-mono/pull/4005) by [@Phoen1xCode](https://github.com/Phoen1xCode)).
 - Added model-level `thinkingLevelMap` support in `models.json` and `pi.registerProvider()`, allowing models to expose only the thinking levels they actually support ([#3208](https://github.com/badlogic/pi-mono/issues/3208)).
