0:00 / 1:06ai Study Claims GPT-5.5 Hallucinates Far More Than GLM-5.2
A new analysis suggests that OpenAI's GPT-5.5 produces hallucinated answers about three times more often than the MIT-licensed GLM-5.2 model, according to results from the AA-Omniscience benchmark. The findings challenge the assumption that larger, more data-rich models are inherently less prone to hallucination, and raise questions about the trade-offs between model size, accuracy, and the ability to admit uncertainty. However, commenters point out that the benchmark only measures hallucination when the model doesn't know the answer, and that overall accuracy and real-world use may differ.
Discussion: Mixed — The discussion is divided: some are skeptical of the study's claims and methodology, while others acknowledge the importance of hallucination rates but stress context and overall accuracy. There is concern about drawing broad conclusions from selective benchmarks. (model size vs. hallucination, benchmark limitations, accuracy vs. abstention)
