OpenAI researches why language models hallucinate and how to explain their neurons

OpenAI has published research addressing two key challenges in large language models: hallucinations and interpretability. Their paper on hallucinations argues that current evaluation methods incentivize models to guess rather than admit uncertainty, leading to confident but false statements. To combat this, they propose penalizing confident errors more heavily than uncertainty. In parallel, OpenAI has developed a method using GPT-4 to automatically generate and score natural language explanations for the behavior of individual neurons within language models, releasing a dataset for GPT-2 to aid interpretability research.

    Language models can explain neurons in language models

    We use GPT-4 to automatically write explanations for the behavior of neurons in large language models and to score those explanations. We release a dataset of these (imperfect) explanations and scores for every neuron in GPT-2.
