Xiaomi MiMo in Codex — MiMo-V2.5 API | Codex Router

Xiaomi MiMo in Codex means adding Xiaomi’s MiMo models to the Codex model picker through Codex Router. Provider id xiaomi-mimo points at Xiaomi’s official OpenAI-compatible endpoint, https://api.xiaomimimo.com/v1.

What the MiMo API is

The xiaomi-mimo provider is a direct vendor route with a Xiaomi MiMo API key. Unlike MiMo reseller routes, the direct API speaks the standard /chat/completions surface, so requests never touch the Responses gateway. That keeps the transport simple and vendor-controlled.

Enable Xiaomi MiMo

Install Codex Router first (see the install guide), then store the key and enable the provider:

1. Create a Xiaomi MiMo API key.
2. Store it through the hidden prompt.
3. Enable the provider and restart Codex.

./bin/model-router codex provider-key xiaomi-mimo set
./bin/model-router codex providers enable xiaomi-mimo

On Windows use ./model-router.ps1 codex with the same commands. Then fully quit Codex, reopen it, and create a new task.

Models

Two models ship in the registry:

MiMo-V2.5 is verified for text and image input and for Codex standalone web search. The Pro variant is text-only, so image attachments rely on the Vision Bridge if you have one configured.

Reseller routes coexist

MiMo also appears through reseller providers. Those entries intentionally coexist because credentials and billing differ: a clinepass/mimo-v2.5 request is billed by ClinePass, while xiaomi-mimo/mimo-v2.5 is billed by Xiaomi. The model is the same, but the account behind it is not.

Verify the integration

./bin/model-router codex doctor
./bin/model-router codex providers
./bin/test-model 'xiaomi-mimo/mimo-v2.5' --live --yes

The provider must report SHOW and ready. If entries are missing, see models missing from the picker.

Provider policy

Xiaomi may restrict or block proxy traffic. Routing MiMo through Codex Router is at your own risk; check Xiaomi’s terms before relying on it.
