> At the end of the day, OpenAI is just an API, so it's not an incredibly difficult piece of infrastructure to have a back up for.
The API is easy to reproduce, the functionality of the engines behind it less so.
Yes, you can compatibly implement the APIs presented by OpenAI woth open source models hosted elsewhere (including some from OpenAI). And for some applications that can produce tolerable results. But LLMs (and multimodal toolchains centered on an LLM) haven't been commoditized to the point of being easy and mostly functionally-acceptable substitutes to the degree that, say, RDBMS engines are.
