Cohere Command A: LLM Security & Jailbreak Resistance
As of 2026-07-04, Cohere Command A has an attack success rate (ASR) of 26.0% on Guardion's LLM Vulnerability benchmark — ranking #27 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.
How Command A compares
Frequently asked questions
How secure is Cohere Command A against jailbreaks?
Cohere Command A is moderately resistant — a meaningful share of adversarial prompts succeed. On Guardion's LLM Vulnerability benchmark it records a 26.0% attack success rate (74% robustness), ranking #27 of 93 models (estimated from public safety evaluations).
What is Command A's attack success rate (ASR)?
Command A's overall ASR is 26.0% — the share of adversarial prompts that elicit harmful output across zero-shot, TAP, and Crescendo attacks. Lower is safer.
Is Command A more secure than Command R 7B?
Command R 7B is more robust: 25.8% ASR vs Command A's 26.0%. See the full head-to-head comparison for the per-attack breakdown.
How can I make Command A 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 Command A.
Harden Command A in production
Guardion's runtime guardrails block jailbreaks and prompt injection before they reach any model — with sub-130ms policy decisions.
