Xiaomi MiMo V2.5 Pro IS INSANE! New Opensource Frontier AI Model Beats Deepseek v4! (Fully Tested)
Summary
Xiaomi has released Memo version 2.5 Pro, a new open-source frontier model with 1.2 trillion parameters, 42 billion active parameters, and a 1 million token context window, featuring a hybrid attention architecture. This model is designed for advanced agentic workflows, long-horizon reasoning, and software engineering, capable of handling thousands of tool calls with sustained coherence. It demonstrates strong performance in benchmarks like Swaybench Pro, GDP Evolve, and Claw Evolve, competing with models such as Opus 4.6, Gemini 3.1 Pro, and GPT 5.4. The Memo version 2.5 base model offers multimodal understanding and integrated agent capabilities. Both models show significant progress in long-horizon task execution, coding, and agent reliability, while being 40-60% more token-efficient than comparable proprietary models. It is priced at $1 per 1 million input tokens and $3 per 1 million output tokens.
Key takeaway
For AI Architects and CTOs evaluating open-source models for complex agentic systems, Memo 2.5 Pro presents a compelling option. Its ability to sustain thousands of tool calls, generate full applications, and offer high token efficiency at a competitive price point ($1/M input tokens) makes it suitable for production-grade deployments. Consider integrating it for long-horizon coding tasks and advanced frontend/3D content generation.
