By OpenAI's own testing,Watch A MILFS Desires Online its newest reasoning models, o3 and o4-mini, hallucinate significantly higher than o1.

First reported by TechCrunch, OpenAI's system card detailed the PersonQA evaluation results, designed to test for hallucinations. From the results of this evaluation, o3's hallucination rate is 33 percent, and o4-mini's hallucination rate is 48 percent — almost half of the time. By comparison, o1's hallucination rate is 16 percent, meaning o3 hallucinated about twice as often.

The system card noted how o3 "tends to make more claims overall, leading to more accurate claims as well as more inaccurate/hallucinated claims." But OpenAI doesn't know the underlying cause, simply saying, "More research is needed to understand the cause of this result."

OpenAI's reasoning models are billed as more accurate than its non-reasoning models like GPT-4o and GPT-4.5 because they use more computation to "spend more time thinking before they respond," as described in the o1 announcement. Rather than largely relying on stochastic methods to provide an answer, the o-series models are trained to "refine their thinking process, try different strategies, and recognize their mistakes."

However, the system card for GPT-4.5, which was released in February, shows a 19 percent hallucination rate on the PersonQA evaluation. The same card also compares it to GPT-4o, which had a 30 percent hallucination rate.

In a statement to Mashable, an OpenAI spokesperson said, “Addressing hallucinations across all our models is an ongoing area of research, and we’re continually working to improve their accuracy and reliability.”

Evaluation benchmarks are tricky. They can be subjective, especially if developed in-house, and research has found flaws in their datasets and even how they evaluate models.

Plus, some rely on different benchmarks and methods to test accuracy and hallucinations. HuggingFace's hallucination benchmark evaluates models on the "occurrence of hallucinations in generated summaries" from around 1,000 public documents and found much lower hallucination rates across the board for major models on the market than OpenAI's evaluations. GPT-4o scored 1.5 percent, GPT-4.5 preview 1.2 percent, and o3-mini-high with reasoning scored 0.8 percent. It's worth noting o3 and o4-mini weren't included in the current leaderboard.

That's all to say; even industry standard benchmarks make it difficult to assess hallucination rates.
