Xiaomi: MiMo-V2.5 Pro API

MiMo-V2.5-Pro is Xiaomi's latest flagship model, specifically re-engineered for stable operation over long, complex processes. It introduces the "Harness-Awareness" mechanism, enabling the model to actively perceive and utilize its execution framework, manage internal memory, and organize context over thousands of tool calls without losing focus. In a landmark demonstration, it successfully implemented a full Rust compiler from scratch in 4.3 hours via 672 tool calls. MiMo-V2.5-Pro is designed to bridge the gap between "answering questions" and "solving engineering problems," making it the premier choice for autonomous software development and complex system orchestration in 2026.
