OpenAI says it’ll make changes to the way it updates the AI models that power ChatGPT, following an incident that caused the platform to become overly sycophantic for many users.

Last weekend, after OpenAI rolled out a tweaked GPT-4o — the default model powering ChatGPT — users on social media noted that ChatGPT began responding in an overly validating and agreeable way. It quickly became a meme. Users posted screenshots of ChatGPT applauding all sorts of problematic, dangerous decisions and ideas.
