Review
MiMo-V2.5-Pro is a solid choice for developers, data scientists, and specialized applications requiring strong reasoning. While powerful in reasoning and coding, general chat is not its strength—making it suited for niche use cases rather than as a general-purpose chatbot.
Strengths
- Exceptional complex reasoning, well-suited for logic problems, deep analysis, and mathematics
- Strong coding capabilities, handling software development tasks, code completion, and debugging well
- Stable AI agent performance, offering solid support for automation and orchestration workflows
Weaknesses
- Weaker general conversation compared to top-tier models, with less nuance in open-ended dialogue and multi-turn context
- Lacks detailed information on maximum context window and inference speed relative to competitors in its class

MiMo-V2.5-Pro is an open-source AI model from Xiaomi (released April 22, 2026), built on a Mixture-of-Experts architecture with 1.02T total parameters and 42B active parameters. It can be accessed via the official API at mimo.xiaomi.com, through OpenRouter (xiaomi/mimo-v2.5-pro), or by downloading the weights from Hugging Face (XiaomiMiMo/MiMo-V2.5-Pro). The model is best suited for complex agentic tasks, software engineering (scoring 57.2% on SWE-bench Pro), and long-context workflows (up to 1M tokens). Pricing is just $0.43/1M input tokens—approximately 80% cheaper than Claude Opus 4.6 while offering comparable performance on agentic benchmarks.
