OpenAI is rolling back a recent update to GPT-4o, the default model that powers ChatGPT, following complaints from users that it made the chat bot act like a weirdo."The last couple of GPT-4o updates have made the personality too sycophant-y and annoying (even though there are some very good parts of it), and we are working on fixes asap, some today and some this week," said OpenAI CEO Sam Altman in a X post spotted by .As of midday Tuesday, Altman said ChatGPT was running on an older, less sycophantic version of GPT-4o for all free users.The company hopes to get paid users back on an older release of the model by later today.
"We're working on additional fixes to model personality and will share more in the coming days," Altman said, adding OpenAI would share more information about what went wrong "at some point."OpenAI released the new GPT-4o late last week.By the weekend, people began noticing ChatGPT was being overly agreeable and verbose in its praise.As you can see from the X post below, often that praise was also inappropriate and strange.When is OpenAI pulling the plug on the new GPT-4o ?This is the most misaligned model released to date by anyone.This is OpenAI's Gemini image disaster moment.image credit : r/u/Trevor050 pic.twitter.com/kNcdnEYMDq— AshutoshShrivastava (@ai_for_success) April 27, 2025Improving the emotional intelligence of its models, in so far as an algorithm can posses the trait, has been a recent focus for OpenAI.
For instance, with GPT-4.5, the company said the model was better at responding with warmth and understanding than its previous systems.In trying to bring that same capability to the more affordable GPT-4o, it seems OpenAI got something wrong.
