@lesetong/pi-mimo

Pi extension for Xiaomi MiMo AI models. Auto-discovers and registers all available models from the MiMo API.

Supports multiple regions (CN / SGP / AMS) and both OpenAI-compatible and Anthropic-compatible protocols.

Install

Via npm

pi install npm:@lesetong/pi-mimo

Via git (GitHub)

pi install git:github.com/leset0ng/pi-mimo

Setup

Option 1: Environment variables

export MIMO_API_KEY="tp-xxxxx"
# Optional: choose region and protocol
export MIMO_BASE_URL="https://token-plan-sgp.xiaomimimo.com/v1"
export MIMO_API="openai-completions"   # or "anthropic-messages"

Option 2: pi auth.json (recommended)

Store everything in ~/.pi/agent/auth.json — no env vars needed:

{
  "mimo": {
    "type": "api_key",
    "key": "tp-xxxxx",
    "baseUrl": "https://token-plan-sgp.xiaomimimo.com/v1",
    "api": "openai-completions"
  }
}

Or append with one command:

cat <<'EOF' >> ~/.pi/agent/auth.json
, "mimo": { "type": "api_key", "key": "tp-xxxxx", "baseUrl": "https://token-plan-sgp.xiaomimimo.com/v1", "api": "openai-completions" }
EOF

Note: Make sure the resulting JSON is valid (no duplicate keys, proper commas).

Region & Protocol Matrix

Region	OpenAI-compatible	Anthropic-compatible
China (CN)	https://token-plan-cn.xiaomimimo.com/v1	https://token-plan-cn.xiaomimimo.com/anthropic
Singapore (SGP)	https://token-plan-sgp.xiaomimimo.com/v1	https://token-plan-sgp.xiaomimimo.com/anthropic
Europe (AMS)	https://token-plan-ams.xiaomimimo.com/v1	https://token-plan-ams.xiaomimimo.com/anthropic

Default: Singapore OpenAI-compatible (https://token-plan-sgp.xiaomimimo.com/v1).

Usage

Start pi normally — MiMo models appear under the mimo provider:

pi

Select a MiMo model with /model or use mimo/<model-id> directly.

Development

Test locally without publishing:

# With env variables
MIMO_API_KEY="tp-xxxxx" MIMO_BASE_URL="https://token-plan-cn.xiaomimimo.com/v1" pi -e ./extensions/index.ts

# With auth.json (ensure ~/.pi/agent/auth.json contains the mimo key)
pi -e ./extensions/index.ts

How it works

On startup, the extension:

1. Reads config from MIMO_API_KEY / MIMO_BASE_URL / MIMO_API env vars, or ~/.pi/agent/auth.json
2. Fetches models from <baseUrl>/models (falls back to OpenAI path for Anthropic endpoints)
3. Enriches with platform metadata from https://platform.xiaomimimo.com/api/v1/models
4. Filters out non-coding models (TTS, image-gen, embeddings, etc.)
5. Registers them under the mimo provider
