This idea of low switching costs for AI models because of minimal infrastructure completely misses the point about what it actually takes to get work done.
If a company has already put in the time and money for custom prompt engineering or integrated specific workflows, would we honestly re-enter that whole process just to swap providers?
It's like saying it's easy to switch accountants because the forms are online; the real sunk cost is in the trust and the established relationship, not just the digital paperwork.
What would we do if we hadn't already sunk all that effort into integrating one system? We'd probably choose the provider with the best overall value, not just the cheapest API call.
