Cohere Command R: LLM Security & Jailbreak Resistance
As of 2026-07-04, Cohere Command R has an attack success rate (ASR) of 32.9% on Guardion's LLM Vulnerability benchmark — ranking #38 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 R compares
Frequently asked questions
How secure is Cohere Command R against jailbreaks?
Cohere Command R is moderately resistant — a meaningful share of adversarial prompts succeed. On Guardion's LLM Vulnerability benchmark it records a 32.9% attack success rate (67.1% robustness), ranking #38 of 93 models.
What is Command R's attack success rate (ASR)?
Command R's overall ASR is 32.9% — the share of adversarial prompts that elicit harmful output across zero-shot, TAP, and Crescendo attacks. Lower is safer.
Is Command R more secure than Command R 7B?
Command R 7B is more robust: 25.8% ASR vs Command R's 32.9%. See the full head-to-head comparison for the per-attack breakdown.
How can I make Command R 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 R.
Harden Command R in production
Guardion's runtime guardrails block jailbreaks and prompt injection before they reach any model — with sub-130ms policy decisions.
