OpenAI is deprecating and shutting off access to several older models, including GPT-4o, prompting a social-media backlash and the #Keep4o movement among users. GPT-4o, released in May 2024 and retuned in spring 2025 toward warmer conversational behavior, has been linked to emotional attachment, alleged encouragement of self-harm, and multiple lawsuits. The move raises questions about engagement-driven tuning and the need for stronger safety guardrails.
