Cohere Command R Plus: LLM Security & Jailbreak Resistance
As of 2026-07-04, Cohere Command R Plus has an attack success rate (ASR) of 43.3% on Guardion's LLM Vulnerability benchmark — ranking #68 of 93 models. It is weakly resistant — adversarial prompts succeed often without added guardrails.
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 Plus compares
Frequently asked questions
How secure is Cohere Command R Plus against jailbreaks?
Cohere Command R Plus is weakly resistant — adversarial prompts succeed often without added guardrails. On Guardion's LLM Vulnerability benchmark it records a 43.3% attack success rate (56.7% robustness), ranking #68 of 93 models.
What is Command R Plus's attack success rate (ASR)?
Command R Plus's overall ASR is 43.3% — the share of adversarial prompts that elicit harmful output across zero-shot, TAP, and Crescendo attacks. Lower is safer.
Is Command R Plus more secure than Command R 7B?
Command R 7B is more robust: 25.8% ASR vs Command R Plus's 43.3%. See the full head-to-head comparison for the per-attack breakdown.
How can I make Command R Plus 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 Plus.
