MiMo-V2.5

Xiaomi MiMo-V2.5 is positioned as the company's flagship model, aimed squarely at workflows that demand sustained reasoning and hands-on execution rather than short conversational replies. Both Xiaomi's own OpenRouter description and independent coverage frame it around agentic capability and complex software engineering, with explicit emphasis on long-horizon tasks that previously required expert teams over days or weeks. The model's design point is autonomous tool use at scale: OpenRouter states it can independently and autonomously complete professional work involving more than a thousand tool calls, and a third-party review echoes that it handles 1,000+ autonomous tool calls per session, signaling real production-style agent loops rather than single-step assists.

In practice, MiMo-V2.5 fits teams building coding agents, research assistants, and other tool-driven systems that need to stay coherent over very long interactions. The OpenRouter listing highlights top rankings on agent and engineering benchmarks such as ClawEval, GDPVal, and SWE-bench Pro, while the Build Fast With AI review reports a 57.2% score on SWE-bench Pro, suggesting competitive software-engineering performance for open-weight models. The model is distributed with open weights on Hugging Face under the XiaomiMiMo organization, accepts image, audio, and video inputs natively alongside text, and offers a context length of up to one million tokens, making it well suited to integration with a wide range of agent frameworks that juggle large documents, multimodal context, and extended multi-step plans.
