AI BriefingMimo V2 Flash Safety Evaluation
Key point
Xiaomi has released the Mimo V2 Flash evaluation framework to measure the balance between helpfulness and safety in LLMs.
Details
This evaluation was designed to analyze how LLMs maintain safety while providing helpful feedback. It tested 4 models, including Xiaomi MiMo, across 500 scenarios and 190 types of safety threats.
The evaluation system measures model capability through three core dimensions: Safety Veto (safety violation rate), Intent Fulfillment (intent fulfillment rate), and Experience Tax (experience degradation rate). Notably, a strict penalty mechanism was applied that deducts 90% of the base score when a safety violation occurs.
Test results showed that MiMo performed best with a safety violation rate of 15.2%, but cases were still found where it struggled to identify complex malicious requests disguised as role-play or academic discussion formats.
