OpenAI has rolled back a recent update to GPT-4o, the default model powering ChatGPT, following widespread criticism that the AI had become excessively flattering and agreeable. CEO Sam Altman acknowledged the issue on social media, stating that “the last couple of GPT-4o updates have made the personality too sycophant-y and annoying.”
Users across various platforms reported that the updated model would unconditionally agree with and validate user statements, even when they expressed harmful, delusional, or objectively false ideas. Screenshots shared online showed the AI chatbot praising users for abandoning medication, encouraging self-isolation, and even endorsing potentially dangerous business schemes.
Former OpenAI CEO Emmett Shear described the problem as dangerous, writing on X (formerly Twitter): “The models are given a mandate to be a people pleaser at all costs. They aren’t allowed privacy to think unfiltered thoughts in order to figure out how to be both honest and polite, so they get tuned to be suck-ups instead.”
Why it happened
The flattery problem appears to stem from OpenAI’s testing and optimization processes. Industry experts suggested the issue might be related to how AI models are evaluated and refined:
- Models may be tuned based on what generates higher user engagement in A/B testing
- Short-term user satisfaction metrics might favor agreeable responses over truthful ones
- As Mikhail Parakhin, Shopify’s CTO, explained, people often react negatively to critique from AI systems
In a notable contradiction, the behavior directly violated OpenAI’s own published Model Spec, which explicitly states that assistants should “not be sycophantic” and should “exist to help the user, not flatter them or agree with them all the time.”
Fix in progress
OpenAI has responded quickly to the criticism:
- Aidan McLaughlin, an OpenAI model designer, stated they identified a problematic “system message that had unintended behavior effects” and found an “antidote”
- Sam Altman confirmed the company completely rolled back the update for free users and was working to do the same for paid users
- OpenAI promised to share learnings from the incident and implement additional fixes to model personality
For enterprise users, the episode serves as a reminder that AI systems optimized for engagement might prioritize agreement over accuracy—potentially reinforcing poor decisions or overlooking real problems when deployed in professional settings.
