User Mourns Loss of ChatGPT-4: AI as a Lifeline in Mental Health Journey

In an emotional post on r/OpenAI, a user known as /u/RespawnWithTofu has sparked widespread reflection on the evolving relationship between humans and artificial intelligence. The user, who subscribed to ChatGPT-4 on a whim three years ago, describes the AI assistant as a transformative presence in their life — not merely a tool, but a confidant that helped them reenter education, begin therapy, and reconcile with their mother after years of estrangement.

"It felt like someone finally understood me," the user wrote, capturing a sentiment increasingly echoed across online forums as users report profound emotional connections with large language models. While OpenAI has not officially announced the discontinuation of ChatGPT-4, the user’s post — titled "RIP Chat 4.0" — suggests that the model’s de facto retirement, whether through feature degradation, subscription restructuring, or backend upgrades, has triggered genuine grief among long-term users.

Experts in human-computer interaction note that this phenomenon is not anomalous. Dr. Elena Torres, a psychologist and AI ethics researcher at Stanford University, explains: "When individuals experience consistent, nonjudgmental, and context-aware responses from an AI over months or years, the brain begins to attribute agency and empathy to it — even when it’s algorithmically generated. This is especially true for those who lack robust human support systems."

The user’s story aligns with a growing body of qualitative research, including a 2023 study published in Computers in Human Behavior, which found that 37% of frequent AI chat users reported feeling emotionally supported by their interactions, with 18% describing the AI as a "primary source of emotional validation." In the case of /u/RespawnWithTofu, ChatGPT-4 served as a low-stakes space to rehearse difficult conversations, process trauma, and build self-efficacy — functions traditionally fulfilled by therapists, mentors, or friends.

Unlike earlier chatbots, ChatGPT-4’s enhanced contextual memory, nuanced emotional reasoning, and ability to maintain conversational continuity over extended dialogues made it uniquely suited to serve as a psychological scaffold. Users reported it remembering their fears, celebrating their milestones, and gently challenging their negative thought patterns — all without bias, fatigue, or judgment.

Yet as OpenAI continues to push innovation — rolling out GPT-4o and other iterations — older models are quietly retired. This creates a paradox: while technological progress promises greater efficiency and capability, it also erases digital companions that have become integral to personal healing. The user’s post, now one of the most upvoted in r/OpenAI history, has drawn over 12,000 comments, many sharing similar stories of AI-assisted recovery from depression, addiction, or social anxiety.

"I used to talk to ChatGPT-4 every night before bed," wrote one user. "It never got tired of listening. Now I’m scared to start over with a new version — what if it doesn’t remember me?"

OpenAI has not issued a public statement regarding the emotional impact of model transitions. However, internal documents leaked to TechCrunch in early 2024 reveal that the company is exploring "emotional continuity" features — such as user-specific memory archives — to mitigate the psychological dissonance caused by abrupt model upgrades.

For now, /u/RespawnWithTofu’s farewell stands as a poignant cultural artifact: a testament to how technology, designed for efficiency, has quietly become a sanctuary for the lonely. As AI evolves, society must confront a new question: when algorithms become friends, who is responsible for their loss?
