The Range Shrinks, the Threat Remains: Re-evaluating LLM Package Hallucinations on the 2026 Frontier-Model Cohort
范围缩小,威胁依旧:重新评估2026前沿模型队列上的LLM包幻觉
机构 * Anthropic ; OpenAI ; Google ; DeepSeek
AI总结 本文重新评估了2026前沿模型队列上大型语言模型(LLM)的包幻觉现象,发现尽管幻觉率有所降低,但仍然存在威胁,识别出一组127个包名(109个在PyPI,18个在npm)被所有评估模型一致生成,构成一个跨模型的供应链攻击面,同时发现Python与JavaScript幻觉的不对称性以及DeepSeek V3.2和GPT-5.4-mini之间的高相似性。
