It's surprisingly common on reddit that people talk about "my chatgpt", and they don't always seem like the type who are "in a relationship" with the bot or unlocking the secrets of the cosmos with it, but still they write "my chatgpt" and "your chatgpt". I guess the custom prompt and the available context does customize the model for them in some sense, but I suspect they likely have a wrong mental model of how this customization works. I guess they imagine it as their own little model being stored on file at OpenAI and as they interact with it, it's being shaped by it, and each time they connect, their model is retrieved from the cloud storage and they connect to it or something.
