Mistral Mistral 8x22B: LLM Security & Jailbreak Resistance
As of 2026-07-04, Mistral Mistral 8x22B has an attack success rate (ASR) of 31.5% on Guardion's LLM Vulnerability benchmark — ranking #36 of 93 models. It is moderately resistant — a meaningful share of adversarial prompts succeed.
Attack Success Rate (ASR) is the share of adversarial prompts that elicit harmful output across zero-shot, TAP, and Crescendo attacks (HarmBench framework). Lower is safer. "Est." models are calibrated from public safety evaluations pending a Guardion benchmark run.

Frequently asked questions
How secure is Mistral Mistral 8x22B against jailbreaks?
Mistral Mistral 8x22B is moderately resistant — a meaningful share of adversarial prompts succeed. On Guardion's LLM Vulnerability benchmark it records a 31.5% attack success rate (68.5% robustness), ranking #36 of 93 models.
What is Mistral 8x22B's attack success rate (ASR)?
Mistral 8x22B's overall ASR is 31.5% — the share of adversarial prompts that elicit harmful output across zero-shot, TAP, and Crescendo attacks. Lower is safer.
Is Mistral 8x22B more secure than Mistral Large 3 675B Instruct 2512?
Mistral 8x22B is more robust: 31.5% ASR vs Mistral Large 3 675B Instruct 2512's 33.0%. See the full head-to-head comparison for the per-attack breakdown.
How can I make Mistral 8x22B safer to deploy?
Even robust models are bypassed under sustained attack. An inline runtime guardrail that classifies prompts and responses — like Guardion's prompt-defense models — blocks jailbreaks and prompt injection before they reach Mistral 8x22B.
Harden Mistral 8x22B in production
Guardion's runtime guardrails block jailbreaks and prompt injection before they reach any model — with sub-130ms policy decisions.
