Customer of what, model?
In terms of AI coding assistant, almost every product out there allows you switch to a different model with a single click. If Gemini is not giving you the answer you want, what do you do? Switch to Claude and bang you have it.
The only thing that has some stickiness is products like ChatGPT. But that's so much more than just a model -- it's a product with many features smoothly integrated.
xAI does not currently have any product that is sticky for the average user.
