Study: Commercial LLMs Outperform Open-Weight Models on Security Prompts

A new study analyzing user prompts related to security and privacy in large language models has found that commercial models generally provide higher quality responses than open-weight models. Researchers examined 14,727 security and privacy prompts from the WildChat dataset, categorizing them and performing a thematic analysis on a subset. While models like GPT-5.5 offered good enough responses in 98% of cases, the study noted that even these top performers sometimes produced inconsistent or contradictory answers across multiple runs, potentially misleading users.
