OpenAI, which has rolled back its last week's GPT‑4o update in ChatGPT due to "sycophantic" behaviour, said, "We fell short and are working on getting it right." OpenAI said the update it removed was "overly flattering or agreeable". "We're revising how we collect and incorporate feedback...and we're giving users greater control over how ChatGPT behaves," OpenAI added.
