NoLetMe

Large language models like DeepSeek V4 Pro may experience reasoning style overfitting during training due to differences in preset configurations, leading to performance fluctuations when switching tool directories. Users often struggle to intuitively detect these style changes, posing challenges for debugging and optimization.

The NoLetMe plugin, as a web extension for DeepSeek Harness, displays real-time statistics of characteristic keywords in reasoning blocks within a session sidebar, classifying reasoning styles into efficient, hesitant, or neutral categories, and provides independent judgment through gray testing. It analyzes only reasoning data and runs entirely locally in the browser, ensuring user privacy and security.

This plugin is ideal for daily DeepSeek Harness users, model developers, and performance evaluators, helping them quickly diagnose model reasoning behavior, optimize preset configurations, and enhance user experience and debugging efficiency without relying on external services.
