Xiaomi MiMo

Xiaomi's MiMo model platform with Anthropic Messages API compatibility. Features MiMo-V2-Flash (262K context) and the newly announced MiMo-V2-Pro (flagship reasoning) and MiMo-V2-Omni (multimodal). Backed by Xiaomi's $8.7B AI investment.

Xiaomi MiMo is an emerging AI model platform from Xiaomi Corp., backed by a planned 60 billion yuan ($8.7 billion) AI investment over three years. In March 2026, Xiaomi unveiled three in-house large models: MiMo-V2-Pro (flagship reasoning), MiMo-V2-Omni (multimodal), and MiMo-V2-TTS (speech synthesis), marking an aggressive push into the generative AI space. The MiMo-V2-Pro model ranked 7th globally and 3rd among Chinese models on Artificial Analysis benchmarks, scoring 49 — just behind MiniMax M2.7 and GLM-5 (both at 50). The model development is led by Luo Fuli, who previously contributed to DeepSeek-V2 at DeepSeek and worked at Alibaba's DAMO Academy before joining Xiaomi in November 2025. What made MiMo models famous before their official launch was the 'mystery model' incident on OpenRouter. Xiaomi anonymously submitted MiMo-V2-Pro and MiMo-V2-Omni as 'Hunter Alpha' and 'Healer Alpha' to OpenRouter, where they quickly topped daily usage rankings, generating over 1 trillion token calls. Developers initially speculated the mystery models were from DeepSeek, but Xiaomi revealed itself as the creator on March 19, 2026. MiMo-V2-Flash was the first model released in December 2025, offering competitive reasoning capabilities with a 262K context window. It's open-source and available on Hugging Face. The API uniquely uses Anthropic Messages API compatibility rather than OpenAI format, which OpenClaw handles through its anthropic-messages provider type. For OpenClaw users, Xiaomi MiMo is notable as a rapidly improving Chinese AI platform with competitive models at early-stage pricing. The models specialize in reasoning and agent tasks, fitting well with OpenClaw's agentic workflow. Being a newer entrant, the platform is still building out its API infrastructure, but the model quality — validated by the anonymous OpenRouter testing — is genuinely competitive with established Chinese AI providers.

Use Cases

  • Reasoning-heavy agent workflows with MiMo-V2-Pro (7th globally on benchmarks)
  • Cost-effective daily AI operations with competitive free/low-cost pricing
  • Multimodal tasks combining text and vision through MiMo-V2-Omni
  • Anthropic-compatible API integration for teams already using Anthropic tooling
  • Open-source model experimentation (MiMo-V2-Flash weights on Hugging Face)
  • Early access to a rapidly improving platform backed by $8.7B investment

Tips

  • Start with MiMo-V2-Flash — it's the most stable and available model on the platform.
  • The Anthropic API compatibility means MiMo can be configured similarly to Anthropic in OpenClaw — just different baseUrl and API key.
  • Watch for MiMo models on OpenRouter and other aggregators for easier access with OpenAI-compatible routing.
  • MiMo-V2-Pro is the reasoning powerhouse — use it for complex tasks. MiMo-V2-Flash for speed and daily use.
  • MiMo-V2-Omni adds multimodal (vision) — useful for image analysis and UI screenshot interpretation.
  • Keep an eye on the Xiaomi MiMo GitHub for open-source model weights and updates.

Known Issues & Gotchas

  • Uses Anthropic Messages API format, NOT OpenAI format. Make sure your OpenClaw provider config uses the correct apiType.
  • Very new platform (December 2025 / March 2026 launches). API stability and documentation may be evolving rapidly.
  • Pricing is currently free/competitive to attract users but will likely increase as the platform matures.
  • Model IDs and API endpoints may change as Xiaomi iterates on the platform.
  • MiMo-V2-Pro and MiMo-V2-Omni were just announced March 19, 2026 — API availability may not match all models yet.
  • Platform documentation may be primarily in Chinese. Expect some friction for English-speaking developers.
  • MiMo-V2-TTS (speech synthesis) is a separate API — not available through OpenClaw's chat interface.

Alternatives

Community Feedback

The 'Hunter Alpha' mystery model turned out to be Xiaomi MiMo! It topped OpenRouter's daily usage with 1 trillion+ token calls before anyone knew who made it. Impressive stealth launch.

MiMo-V2-Pro scoring 49 on Artificial Analysis puts it right behind the best Chinese models. For a company known for phones and EVs, that's remarkable AI capability.

The Anthropic API compatibility choice is interesting. Most Chinese providers go OpenAI-compatible. Xiaomi chose Anthropic format, suggesting they're targeting a different developer audience.
