Hallucinations have improved, but the average for all models is still around 8-9%. Likely the study I read before was from last year, so the higher hallucinations rate is from that.
Even the best model hallucinates an average of around 1 in 100 times and OpenAI has stated publicly that hallucinations are mathematically impossible to eliminate entirely.
Where does this 9-13% number come from?
There was a study done several months ago. I’ll try to find the source again and link it here in a comment edit.
[EDIT]
Couldn’t find the study, but here is an infographic that has similar data: https://infogram.com/ai-hellucination-report-2025-1h9j6q7mz7q354g
