Recent research has revealed a troubling trend in artificial intelligence: the "hallucination" problem, where models generate false or misleading information, is getting worse.
Internal tests by OpenAI have found that their latest models, including the o3 and o4-mini versions, are more likely to hallucinate than previous iterations, with the o3 model fabricating information in 33% of factual questions and the o4-mini version in 48%.
