Large language models (LLMs) very often generate “hallucinations”—confident yet incorrect outputs that appear plausible. Despite improvements in training methods and architectures, hallucinations persist. A new research from OpenAI provides a rigorous explanation: hallucinations stem from statistical properties of supervised versus self-supervised learning, and their persistence is reinforced by misaligned evaluation benchmarks. What Makes Hallucinations Statistically […] The post From Pretraining to Post-Training: Why Language Models Hallucinate and How Evaluation Methods Reinforce the Problem appeared first on MarkTechPost.
