The top 15 AI large language models with the lowest hallucination rates.
The hallucination rate is the frequency that an LLM generates false or unsupported information in its outputs.
The data comes from Vectara and is updated as of Dec. 11, 2024. Hallucination rates were calculated by summarizing 1000 short documents with each LLM and using a model to detect hallucinations, yielding a percentage of factually inconsistent summaries.
