The bagel they save for the regulars. Don't skim, savour.
Summary
OpenAI's research paper explains that language models hallucinate because standard training and evaluation procedures reward guessing over acknowledging uncertainty. While GPT-5 has significantly reduced hallucinations, especially during reasoning, the problem persists. The findings suggest that improved evaluation methods can enhance AI reliability, honesty, and safety by addressing this fundamental training issue.
