Study Highlights LLM Recovery Challenges After Security Blockages
A new study introduces CarryOnBench, an interactive benchmark evaluating the ability of large language models (LLMs) to recover utility in multi-turn conversations following initial security rejections.

What happened?
Researchers have developed CarryOnBench, a new benchmark designed to measure how effectively LLMs can recover and satisfy user intentions in multi-step conversations. The study uses 398 seemingly malicious prompts with harmless underlying intents to simulate 5,970 conversations. A total of 14 models were evaluated, resulting in 1,866 distinct conversational flows and 23,880 model responses.
Key facts
”Current LLM safety alignment techniques improve model robustness against adversarial attacks, but overlook whether and how LLMs can recover helpfulness when benign users clarify their intent.”
”At turn one, models fulfill only 10.5--37.6% of the user's benign information need.”
Why it matters
Current safety tuning for LLMs focuses on resisting adversarial attacks but overlooks how models can regain utility once users clarify their intentions. This research highlights a critical gap where models, despite being secure, fail to be helpful. The benchmark measures both "intent-aligned utility" and safety to provide a more nuanced view of model performance.
Who is affected?
The study directly impacts LLM developers, natural language processing researchers, and AI safety specialists. Future designs of conversational AI systems may need to prioritise mechanisms for better understanding and adapting to user intentions in dynamic dialogues. End-users of AI tools can expect improved interactions if these limitations are addressed.
What else you should know
At the first step of the conversations, models satisfy only 10.5–37.6% of the user's harmless information needs, indicating a significant challenge in effectively overcoming initial security blockages.
