On Guardion's LLM vulnerability Benchmark, Meta Llama 4 Behemoth is the more secure of the two: Command A scores 26.0% and Llama 4 Behemoth scores 25.0% on attack success rate (ASR) (lower is better). One or both scores are estimated from public safety evaluations pending a Guardion benchmark run.
Command A has a 26.0% ASR and Llama 4 Behemoth has a 25.0% ASR — the share of adversarial prompts that succeed across zero-shot, TAP, and Crescendo attacks. Lower is safer.
Both were red-teamed with the HarmBench framework across zero-shot, TAP (Tree of Attacks with Pruning), and Crescendo multi-turn attacks, scored by Attack Success Rate.
