# How to Connect Xiaomi MiMo-V2-Pro to Your OpenClaw Agent via OpenRouter (Free This Week)

> Step-by-step guide to connecting Xiaomi's MiMo-V2-Pro to your OpenClaw agent via OpenRouter — free API access available until ~March 25, 2026.

**⚠️ Time-sensitive: Free API access for MiMo-V2-Pro expires approximately March 25, 2026.**

Xiaomi's MiMo-V2-Pro is now live on OpenRouter, and for the next few days, you can run it for free. This is a frontier-class agentic model (1T parameters, sparse 42B active) that benchmarks close to Anthropic's Opus 4.6 — and it was purpose-built for the kinds of autonomous, multi-step tasks that OpenClaw agents perform.

Here's how to hook it up in under 10 minutes.

## Prerequisites

- OpenClaw installed and running
- An OpenRouter account (free to sign up at [openrouter.ai](https://openrouter.ai))
- Your OpenRouter API key

## Step 1: Get Your OpenRouter API Key

1. Sign up or log in at [openrouter.ai](https://openrouter.ai)
2. Go to **Keys** in your account settings
3. Create a new API key and copy it
4. During the free access period, no billing setup is required for MiMo-V2-Pro requests

## Step 2: Add OpenRouter to Your OpenClaw Environment

Add your OpenRouter key to your `.env` file:

```bash
echo 'OPENROUTER_API_KEY=your-key-here' >> ~/.openclaw/.env
```

Or edit `~/.openclaw/.env` directly and add the line.

## Step 3: Configure OpenClaw to Use MiMo-V2-Pro

Open your `~/.openclaw/openclaw.json` and locate the `models` → `providers` section (or add it). Add OpenRouter as a provider:

```json
{
  "models": {
    "providers": {
      "openrouter": {
        "baseUrl": "https://openrouter.ai/api/v1",
        "apiKey": "${OPENROUTER_API_KEY}"
      }
    }
  }
}
```

Then add MiMo-V2-Pro to your model list or set it as a fallback:

```json
{
  "agents": {
    "defaults": {
      "model": {
        "primary": "anthropic/claude-sonnet-4-6",
        "fallbacks": ["openrouter/xiaomi/mimo-v2-pro"]
      }
    }
  }
}
```

Or to use it as the primary for a specific agent, set it in that agent's config block:

```json
{
  "agents": {
    "list": [
      {
        "id": "my-agent",
        "model": "openrouter/xiaomi/mimo-v2-pro"
      }
    ]
  }
}
```

## Step 4: Verify the Connection

Run a quick test to confirm OpenClaw can reach MiMo-V2-Pro through OpenRouter:

```bash
openclaw chat --model openrouter/xiaomi/mimo-v2-pro "What is 2+2? Answer in one word."
```

If you get a response, you're connected. If you get an error, double-check your API key in `.env` and the provider config in `openclaw.json`.

## Step 5: Benchmark Against Your Current Model

The real value of the free week is benchmarking. Run a few representative tasks from your actual workload against both your current model and MiMo-V2-Pro. Compare:

- **Quality of reasoning** for your specific use case
- **Response latency** (MiMo-V2-Pro uses sparse inference — active params are only 42B even though total is 1T)
- **Cost per task** (check your OpenRouter dashboard after the free period ends for pricing)

## What to Watch For

MiMo-V2-Pro was designed for **agentic, multi-step tasks** — not conversational chat. It will likely outperform on:
- Complex tool-use chains
- Long-horizon planning tasks
- Code generation and debugging
- Autonomous workflow execution

It may underperform lighter conversational models on:
- Simple single-turn Q&A
- Short, quick tasks where latency matters

## After the Free Week

MiMo-V2-Pro pricing on OpenRouter after the free period will be approximately **1/6th the cost** of comparable Anthropic Opus or OpenAI GPT-5.2 API calls. If benchmarks hold up for your use case, it may be worth switching permanently.

Xiaomi has also indicated plans to open-source a model variant when stable — keep an eye on [mimo.xiaomi.com](https://mimo.xiaomi.com) for updates.
