MiMo V2.6: select Pro or Flash for Hermes and OpenClaw

Select MiMo V2.6 from your instance card

MiMo V2.6 is available on OpenRouter, and its Pro, Flash and Pro-UltraSpeed entries are visible in the OpenClaw Launch model selector. The steps below are the same for Hermes Agent and OpenClaw. You can keep your existing instance.

1. Open the dashboard and find your running instance.
2. Click the current model in the Text or Model row on the instance card.
3. Choose OpenRouter in the provider list. Check whether you are using account credits or the Your key route before selecting a model.
4. Search for mimo. The search includes All OpenRouter models, beyond the featured list. Choose MiMo-V2.6-Flash, MiMo-V2.6-Pro, or MiMo-V2.6-Pro-UltraSpeed.
5. Wait for the model change to finish and the instance to become ready. Confirm the new name on the card before resuming work. Start a fresh conversation if an existing session retains its previous model.

The full catalogue is available on eligible paid instances. Trial accounts use a restricted model list. If account credits are exhausted, add credits or configure your own OpenRouter API key on the API keys page. With an active personal OpenRouter key, usage is charged to that OpenRouter account; it does not become free usage.

What changed in MiMo V2.6?

Xiaomi announced MiMo V2.6 Pro and Flash as open-source, native multimodal models. Its official release announcement focuses on improvements to agent tasks and reinforcement learning. OpenRouter lists text, image, audio and video input with text output, plus tool calling and reasoning support.

For a hosted agent, the practical change is access to a new reasoning and tool-calling model through the existing selector. Available media inputs still depend on the channel and agent integration forwarding those inputs. Selecting MiMo as the text model does not configure the separate image, video or music generation tools.

Pro, Flash or UltraSpeed?

These are OpenRouter's listed uncached input and output prices, checked September 22, 2026 (UTC), not the hosting subscription price. All three catalogue entries list a 1,048,576-token context window. Provider availability, routing and pricing can change; check the linked model page before a large run.

Flash is the lower-cost starting point for routine chat, summaries and repeated tasks. Pro is worth comparing on your own difficult coding or multi-step tasks before choosing a default. UltraSpeed is the speed-focused Pro edition; its listed input and output rates are 10 times Pro's, so choose it deliberately when response time matters. These are practical selection suggestions, not a claim that one model wins every task.

If the model does not appear

• Make sure you selected the OpenRouter provider, then search mimo rather than looking only at the featured models.
• Refresh the dashboard if it was already open when the model launched. Catalogue updates can take time to appear.
• Check your trial status, available credits and which API-key route is active.
• If the card changes but a conversation still uses the old model, wait for readiness and start a fresh session. If a request fails, check the selected key's balance and OpenRouter provider availability before switching again.

MiMo V2.6 has separate IDs from V2.5. An instance using V2.5 does not switch to V2.6 merely because the new model has been released.

Self-hosted Hermes Agent

On your own Hermes installation, run hermes model, choose OpenRouter, supply your own OpenRouter API key when prompted, and select or enter xiaomi/mimo-v2.6-pro. Use the Flash ID for the lower-cost model.

The model section in ~/.hermes/config.yaml is:

model:
  provider: openrouter
  default: xiaomi/mimo-v2.6-pro

Keep your key in the supported OPENROUTER_API_KEY environment setting or Hermes credential setup. Hermes stores the provider separately, so its model value does not need an extra openrouter/ prefix. Start a new session after changing the default. See the upstream Hermes configuration example.

Self-hosted OpenClaw

For a self-hosted OpenClaw installation, configure your own OpenRouter key through onboarding, then set the model:

openclaw onboard --auth-choice openrouter-api-key
openclaw models set openrouter/xiaomi/mimo-v2.6-pro

The corresponding model section in ~/.openclaw/openclaw.json is shown below. Merge this section into your existing configuration; it is not a replacement for the complete file.

{
  "agents": {
    "defaults": {
      "model": { "primary": "openrouter/xiaomi/mimo-v2.6-pro" }
    }
  }
}

OpenClaw uses the extra openrouter/ provider prefix. Follow the official OpenRouter setup documentation for credentials. Managed OpenClaw Launch users can use the instance-card steps above without editing these files.

Frequently asked questions

Does MiMo V2.6 work with Hermes Agent?

Yes. Hermes Agent can use MiMo V2.6 through OpenRouter. On OpenClaw Launch, Hermes and OpenClaw share the instance-card model selector; select OpenRouter and search mimo.

Do I need a new instance or a Xiaomi API key?

No new instance is required. The OpenRouter route uses eligible account credits or your own OpenRouter key. A direct Xiaomi API key is not required for this route.

Is MiMo V2.6 free because it is open source?

Open-source availability does not make hosted API inference free. OpenRouter lists token prices for these models, and hosting is billed separately.

Will my MiMo V2.5 instance upgrade automatically?

No. V2.6 uses separate model IDs. Select the desired V2.6 entry on the instance card and wait for the change to finish.
