MiMo V2.5 Pro UltraSpeed

MiMo-V2.5-Pro-UltraSpeed is Xiaomi’s ultra-fast, text-based flagship reasoning model, pairing a trillion-parameter model with a 1,048,576-token context window and generation speeds of roughly 500–1,000 tokens per second. It supports deep thinking, tool calling, streaming output, and context caching, making it well suited to latency-sensitive coding agents, quantitative analysis, real-time risk control, and scientific workflows.
