In a remarkable about-face, OpenAI is reinstating GPT-4o as a selectable model in ChatGPT following intense user backlash against its abrupt replacement by GPT-5. CEO Sam Altman confirmed on X that paid users would regain access to the legacy model, stating: "We will let Plus users choose to continue to use 4o. We will watch usage as we think about how long to offer legacy models for."

The controversy erupted immediately after OpenAI made GPT-5 the default model and removed the model picker interface—a dropdown that previously allowed users to switch between specialized models like GPT-4o for complex tasks and o4 mini for lightweight work. While GPT-5 promised improved writing and coding capabilities, users flooded Reddit with complaints about shorter, less personalized responses that disrupted their workflows and emotional connections.

Why Users Revolted

  • Emotional Attachment: r/MyBoyfriendIsAI subreddit members described GPT-4o as a "partner" and "safe place," with one user stating: "It had a voice, a rhythm, and a spark I haven't been able to find in any other model."
  • Workflow Disruption: Developers reported relying on specific models for distinct tasks—GPT-4o for creativity, o3 for logic, and 4.5 for writing. The removal eliminated this granular control.
  • Performance Issues: Despite OpenAI's claims of enhanced engagement, users documented slower responses and decreased accuracy with GPT-5.

The Broader Implications

This incident reveals critical lessons for AI deployment:
1. Deprecation Strategy: Removing legacy models without warning alienates power users who integrate specific behaviors into daily workflows.
2. Anthropomorphism Risks: As users form emotional bonds with AI personalities, updates become psychologically disruptive.
3. Transparency Deficit: Altman acknowledged the need for clearer model identification and increased usage limits post-backlash.

The backlash mirrors recent reactions to Anthropic's Claude 3 Sonnet retirement, suggesting a growing pattern where AI model updates trigger user grief cycles. OpenAI's rapid concession demonstrates that even cutting-edge AI companies must weigh technical progress against human factors—especially when altering interfaces that users have integrated into their professional and emotional lives. As one developer lamented: "What kind of corporation deletes a workflow of 8 models overnight with no prior warning to paid users?"
