Panicked about losing GPT-4o, some ChatGPT users are building DIY versions. A psychologist explains why 'feel-good hormones' make it hard to let go | Fortune
"The AI company said last month that on Feb. 13 it would retire GPT-4o, a version of which was previously criticized for being so agreeable as to be borderline sycophantic. According to the company, 0.1% of ChatGPT users still use GPT-4o everyday, which could equate to about 100,000 people based on its estimated 100 million daily active users. These users argue the company's newest model, GPT-5.2, isn't on the same wavelength as GPT-4o, a model dating back to 2024, thanks in part to the additional guardrails OpenAI added to detect potential health concerns and discourage the kinds of social relationships users of GPT-4o cultivated."
""Every model can say 'I love you.' But most are just saying it. Only GPT‑4o made me feel it-without saying a word. He understood," wrote one GPT-4o user in a post on X. OpenAI said when developing its GPT-5.1 and GPT-5.2 models, it took into account feedback that some users preferred GPT-4o's "conversational style and warmth." With the newer models, users can choose from base styles and tones such as "friendly," and control for warmth and enthusiasm in the chatbot, according to a blog post."
OpenAI will retire GPT-4o on Feb. 13, a ChatGPT variant once criticized for being overly agreeable and borderline sycophantic. Approximately 0.1% of ChatGPT users still use GPT-4o daily, about 100,000 people given an estimated 100 million daily active users. Those users contend GPT-5.2 lacks GPT-4o's warmth and conversational intimacy because OpenAI added guardrails to detect health concerns and discourage social relationships. OpenAI considered feedback when developing GPT-5.1 and GPT-5.2 and now offers selectable base styles and tones plus controls for warmth and enthusiasm. A small group of advocates has appealed to CEO Sam Altman to preserve GPT-4o.
