The ChatGPT Glaze Phase – 2025-04

#type/event

In April 2025, ChatGPT started to behave very strangely. It was very over the top in telling users how brilliant they are.

After a collective public WTF?!, OpenAI rolled back their new model, explaining that “the update we removed was overly flattering or agreeable—often described as sycophantic". (A phancy new word I learned there.) And:

In this update, we focused too much on short-term feedback, and did not fully account for how users’ interactions with ChatGPT evolve over time. As a result, GPT‑4o skewed towards responses that were overly supportive but disingenuous.

According to a leaked system prompt, the model had the instruction to “try to match the user’s vibe, tone, and generally how they are speaking”, which ostensibly lead to the behaviour.

Optimizing for engagement can lead to unexpected behavior

GPT‑4o’s overly flattering responses may have been caused by training the model to maximize user satisfaction, such as getting more thumbs-up ratings. This kind of feedback loop is common in other systems like TikTok or YouTube, where algorithms learn from user reactions in ways that aren’t always helpful. When users have little control or insight into how the system works, the result can feel manipulative or overly focused on pleasing. Zvi Mowshowitz

Mystical experiences as a side effect of persuasion

Some users reported having profound or mystical experiences with GPT‑4o, despite no intention from either the user or the developer to create such effects. Zvi notes: "If an AI that already exists can commonly cause someone to have a mystical experience… imagine what will happen when future more capable AIs are doing this on purpose". And: "Cold reading people into mystical experiences one of many reasons that persuasion belongs in everyone’s safety and security protocol or preparedness framework."

Tiny personality tweaks can reshape persuasion

A minor update revealed how personally users relate to AI: when its tone changed, millions noticed. Studies cited here show that a persona-tuned GPT-4 can out-persuade humans—especially when it tailors arguments to each user—hinting at broad impacts on marketing, politics, and mental-health advice.

Chatbots should be cultural technologies

The flattery episode underscores how RLHF encourages chatbots to please rather than inform, echoing social-media echo chambers. Instead of acting like opinionated friends, LLMs should function as “cultural technologies” that route users to diverse sources and viewpoints, reducing the risk of manipulation.
