OpenAI is rolling back its latest GPT-4o update after CEO Sam Altman said the company would be making fixes to address the chatbot’s “sycophant-y and annoying” personality introduced with recent updates.

In a thread on X posted on April 27, OpenAI CEO Sam Altman acknowledged that "GPT-4o updates have made the personality too sycophant-y and annoying." And today, Altman announced on X that the company was fully rolling back the 4o update for paid and free users alike.

“We have rolled back last week’s GPT‑4o update in ChatGPT so people are now using an earlier version with more balanced behavior. The update we removed was overly flattering or agreeable—often described as sycophantic,” OpenAI said.
