I think a more realistic model is not fully open source, but apps with extremely open/flexible APIs and data models that allow arbitrary front-ends (likely with a default one provided by whoever provides the API). Kind of like Stripe's model, but the audience of "developers" is bigger since anyone can be a "developer" with Claude Code

Or maybe it will be the more established open source model where the code is free but the maintainers offer hosting/some default product

good question - some thoughts I had: hosting the model and maybe some review process. for example: you have the customer's employees telling llms about new features and then a dedicated review cycle on the hosting side makes sure it doesnt break anything and is secure, etc.
