A recent experiment tested the effectiveness of LLM guardrails by evaluating a system with an input classifier, a core model (openai/gpt-oss-120b), and an output classifier. The test involved 34 prompts categorized as benign, borderline-benign, and jailbreak attempts. The experiment found that guardrails can be overly restrictive, blocking legitimate queries, and that the policy itself is the critical element to engineer for effective safety. AI
IMPACT Highlights the trade-offs between LLM safety and usability, suggesting that effective guardrails require careful policy engineering.
