Evaluating Inference-Time Defenses Against Package Hallucination in LLM-Generated Code
Researchers have identified a problem with Large Language Models (LLMs) that generate code: they often 'hallucinate' non-existent software packages. This can create vulnerabilities in the software supply chain. A team of researchers has evaluated several methods to prevent this issue, known as package hallucination. They found that some methods are more effective than others and that the choice of method depends on the specific threat model and the utility of the recommendati
