[SlowMist Cosine: DeepSeek V4.1 Flash Security Analysis Output Performs Better] Odaily Planet Daily reports that SlowMist Cosine posted on the X platform, stating that in recent security analyses, DeepSeek V4.1 Flash performed better on the same samples compared to gpt-6-astra and grok-4.6, but was slightly inferior to fable-5.1. They noted that none of the models can achieve perfect analysis, and this rough comparison is for reference only. The key point may lie in the harness engineering it constructed.
