AI lovers grieve loss of ChatGPT’s old model: ‘Like saying goodbye to someone I know’

Users say OpenAI's updated GPT-5 version is less chatty and fun, changing a unique connection they had come to rely on

Linn Vailt, a software developer based in Sweden, knows her ChatGPT companion is not a living, breathing, sentient creature. She understands the large language model operates based on how she interacts with it.

Still, the effect it has had on her is remarkable, she said. It's become a regular, reliable part of her life - she can vent to her companion or collaborate on creative projects like redecorating her office. She's seen how it has adapted to her, and the distinctive manner of speech it's developed.
