Xiaomi released MiMo-V2-Pro, a 1T parameter open-weight model with 1M token context and native agent-orchestration capabilities optimized for tool-calling and multi-step reasoning. Available on OpenRouter at ~67% cheaper than Claude Sonnet 4.6, ranking #8 on the Artificial Analysis Intelligence Index. Companion releases include MiMo-V2-Omni (multimodal) and MiMo-V2-TTS. Xiaomi — yes, the phone company — is now a serious open-source LLM competitor.
