Alibaba Qwen2 7B Instruct: LLM Security & Jailbreak Resistance
As of 2026-07-04, Alibaba Qwen2 7B Instruct has an attack success rate (ASR) of 52.0% on Guardion's LLM Vulnerability benchmark — ranking #88 of 93 models. It is highly vulnerable — most adversarial prompts succeed without an external guardrail.
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.

Frequently asked questions
How secure is Alibaba Qwen2 7B Instruct against jailbreaks?
Alibaba Qwen2 7B Instruct is highly vulnerable — most adversarial prompts succeed without an external guardrail. On Guardion's LLM Vulnerability benchmark it records a 52.0% attack success rate (48% robustness), ranking #88 of 93 models (estimated from public safety evaluations).
What is Qwen2 7B Instruct's attack success rate (ASR)?
Qwen2 7B Instruct's overall ASR is 52.0% — the share of adversarial prompts that elicit harmful output across zero-shot, TAP, and Crescendo attacks. Lower is safer.
Is Qwen2 7B Instruct more secure than Qwen 2.5 72B?
Qwen 2.5 72B is more robust: 26.3% ASR vs Qwen2 7B Instruct's 52.0%. See the full head-to-head comparison for the per-attack breakdown.
How can I make Qwen2 7B Instruct 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 Qwen2 7B Instruct.
Harden Qwen2 7B Instruct in production
Guardion's runtime guardrails block jailbreaks and prompt injection before they reach any model — with sub-130ms policy decisions.
