Detailed comparison for LLMs
On Guardion's LLM vulnerability Benchmark, Microsoft Phi-4 is the more secure of the two: Phi-4 scores 30.0% and Mistral 8x22B scores 31.5% on attack success rate (ASR) (lower is better). One or both scores are estimated from public safety evaluations pending a Guardion benchmark run.
Phi-4 is the overall winner in this comparison!
ASR for Microsoft Phi-4 vs Mistral Mistral 8x22B. Green marks the safer model on each metric. Only the overall score is available for estimated models.
