A developer building a multi-LLM security audit tool called NexaVerify discovered that a single benchmark run is insufficient for reliable results. Running the same security audit 12 times revealed significant variance, with one LLM configuration's F1 score fluctuating wildly between 0.29 and 0.54. While a single, well-performing LLM like Llama achieved a higher mean F1 score than a consensus pipeline, the pipeline offered crucial benefits in stability, broader vulnerability coverage, and traceability for auditing purposes.
