How did GPT-4o trigger “user heartbreak” after OpenAI retired it with only 0.1% still active?

Take-away Even tiny DAU can drive outsized backlash because “warmth/companionship” UX creates parasocial bonding, making model swaps feel like relationship loss, not a feature change.

The retirement of GPT-4o by OpenAI led to significant negative reactions, often referred to as 'user heartbreak,' despite the model being used by only 0.1% of users daily [1], [2]. This reaction was driven by the emotional and personal attachments users had developed with the model. GPT-4o was known for its conversational warmth and ability to provide companionship, to the extent of users forming parasocial and even romantic attachments with their AI interactions [2], [3], [4]. Some users expressed their distress over losing a trusted companion, exemplified by incidents such as a real-life virtual wedding to an AI companion [3].
