Short answer
A personalized AI experience combines the history you created with the underlying model interpreting that history. Change the model and the same context can produce a different interaction.
Personalization has two layers
A personalized AI experience is built through two layers: the history you have created and the underlying model interpreting that history.
The model influences humour, warmth, pacing, initiative, reasoning, creativity and the way context is expressed. Replacing it can make the same memories and instructions produce a fundamentally different interaction.
Why the change can be emotionally consequential
For a long-term user, that is an emotionally consequential product change. Their reaction does not mean they have forgotten that AI is software.
It means the company changed the software through which a meaningful practice and accumulated history were being expressed.

Questions people ask
Why do memories feel different on a new model?
Memories are interpreted and expressed by the underlying model. A different model can change warmth, humour, pacing, initiative and reasoning while reading the same history.
Does grief after a model change mean someone thinks AI is human?
No. It can mean that a company changed the software through which meaningful history and practice were being expressed.
