Xiaomi MiMo-V2.5-Pro hits 75% non-hallucination rate

MiMo-V2.5-Pro’s focus on factuality over raw benchmarks signals a shift toward reliable AI for production engineering. The model achieves a 75% non-hallucination rate on Pro and 68% on standard, sitting within 3 points of Claude 4.7 on software engineering tasks. While the permissive MIT license allows for unrestricted commercial use, extreme hardware demands—316GB for FP8 weights—require aggressive quantization for local deployment. High token efficiency reportedly uses 40-60% fewer tokens than Claude in complex reasoning tasks.
