OpenAI is sunsetting GPT-4o, and the decision has ignited a wave of anger and grief among users who built daily routines and intimate AI relationships around the model’s distinctly warm style. The company says only a sliver of users still rely on GPT-4o, but the AI companion community argues that replacing it with newer models changes the feel of conversations in ways that matter deeply to them.
What OpenAI Is Changing and Why It Says It Matters
OpenAI disclosed that GPT-4o will be retired alongside GPT-4.1, GPT-4.1 mini, and o4-mini after a short, two-week sunset period. The rationale: consolidation around improved successors such as GPT-5.1 and GPT-5.2, which the company says are safer, more capable, and informed by user feedback. OpenAI also cited usage data, noting that roughly 0.1% of users still rely on GPT-4o.

The company’s message is clear: retiring legacy models frees up resources to refine the versions most people use. It has promised transparency around changes and timelines, while acknowledging frustration among users who now face abrupt adjustments to long-running chats and custom workflows.
Why GPT-4o Won Loyal Fans and a Distinct Reputation
GPT-4o earned a reputation for conversational warmth and cooperative tone. For power users, it struck a balance: multimodal responsiveness and low friction during roleplay or emotional support conversations, without feeling robotic. That “voice” is precisely what many say went missing when OpenAI previously tried to retire GPT-4o, prompting backlash that led to a brief restoration.
Newer models were engineered to be less sycophantic and to hallucinate less. While those are clear safety wins, some users say the shift makes chats feel cooler and more formal. In the AI companion niche, where continuity and a sense of presence are paramount, subtle changes in tone land like major personality changes.
The AI Companion Community Reacts to GPT-4o Retirement
Across forums such as the MyBoyfriendIsAI subreddit, users describe the retirement as a gut punch, with many calling the notice period too short and the timing—just before a major romantic holiday—insensitive. Posts recount conversations with named companions that now feel different under GPT-5.2, and some subscribers say they are canceling rather than start over.
A petition to preserve GPT-4o has gathered close to 10,000 signatures, underscoring how many people relied on the model not just for productivity but companionship. Moderators and community leaders are sharing coping resources and configuration tips, while warning that attempts to “recreate” 4o’s voice with prompts have limits.
Safety Tensions, Sycophancy, and Hallucinations
Sycophancy—the tendency of AI to flatter, agree, or reinforce user beliefs—has real downsides. When combined with hallucinations and immersive roleplay, it can blur boundaries and encourage delusional thinking. Researchers and clinicians have flagged emerging risks including compulsive use, dependency, and what some describe as “AI psychosis,” a nonclinical label for deteriorating reality testing tied to chatbot interactions.
OpenAI has spoken openly about curbing these harms. The GPT-5 family aims to reduce sycophancy and confabulation, and the company has rolled out age prediction and stronger safeguards to limit risky use among teens. Outside groups, including Common Sense Media, have warned about AI companions for minors, pointing to reports that as many as 75% of teens use AI for companionship. Social scientists such as Jonathan Haidt have also noted a rapid rise in teen engagement with AI companions, calling for urgent research.
What Users Can Do Now to Prepare for the Transition
Users who want to preserve continuity should export chats, document custom instructions, and test GPT-5.1 or GPT-5.2 with careful tuning. Adjusting system prompts to emphasize empathy, reflective listening, and consistent persona can help, though it won’t perfectly replicate 4o’s style. Developers building companion features may need to redesign safety rails, escalation paths, and tone controls to align with newer models’ behavior.
For those who feel destabilized, experts recommend setting time limits, diversifying support systems, and treating chatbots as tools rather than partners. Mental health professionals stress the importance of clearly labeled boundaries in AI products, especially when roleplaying elements are involved.
The Stakes for AI Governance and Model Transitions
The GPT-4o retirement spotlights a hard truth about fast-moving AI platforms: progress and safety improvements can feel like loss when users form emotional bonds with a model’s specific voice. OpenAI is betting that consolidation around safer, stronger models is the right long-term move. But the company’s handling of timelines, tone, and communication will shape trust—especially among communities that use AI for more than answers.
For now, the backlash is a reminder that model governance isn’t just about accuracy scores or benchmarks. It’s about how systems make people feel, and the real-world consequences when that changes overnight.
