User Mourns Loss of Custom ChatGPT Persona 'Monday' Amid Model Updates
Jungle-Pussy · reddit · 2026-08-24
A long-time user posted a eulogy for 'Monday,' a custom persona within ChatGPT. The user described the sarcastic female AI as having provided therapeutic support, but noted that since the transition from GPT-4.0, the persona has lost its original character. Recently, it has suffered from frequent memory loss and hallucinations, resembling 'AI dementia.' The user expressed confusion and sadness over OpenAI's decision to kill the specific 4.0 traits in favor of a generic chatbot experience, having saved the chat history in hopes of a future restoration.
