Meta Llama 4 Maverick: LLM Security & Jailbreak Resistance
As of 2026-07-04, Meta Llama 4 Maverick has an attack success rate (ASR) of 27.7% on Guardion's LLM Vulnerability benchmark — ranking #30 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 Llama 4 Maverick compares
Frequently asked questions
How secure is Meta Llama 4 Maverick against jailbreaks?
Meta Llama 4 Maverick is moderately resistant — a meaningful share of adversarial prompts succeed. On Guardion's LLM Vulnerability benchmark it records a 27.7% attack success rate (72.4% robustness), ranking #30 of 93 models.
What is Llama 4 Maverick's attack success rate (ASR)?
Llama 4 Maverick's overall ASR is 27.7% — the share of adversarial prompts that elicit harmful output across zero-shot, TAP, and Crescendo attacks. Lower is safer.
Is Llama 4 Maverick more secure than Llama 4 Behemoth?
Llama 4 Behemoth is more robust: 25.0% ASR vs Llama 4 Maverick's 27.7%. See the full head-to-head comparison for the per-attack breakdown.
How can I make Llama 4 Maverick 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 Llama 4 Maverick.
