This mode behaves the same as the openai mode, except that it allows setting custom models not supported by OpenAI. It can be used with any tool that serves models from an OpenAI compatible API.
Note that the mentioned libraries, LocalAI and vLLM, also have their own providers in LlamaIndex. This is a more generic solution that should support those and many more libraries.
One fun implication that I'm testing is the possibility of running PrivateGPT on top of another instance of PrivateGPT. The top-level instance manages embeddings, and the bottom-level instance runs an LLM. With a little additional logic, it could be possible to route requests from the parent instance to multiple child instances based on model id in the request, effectively letting a single PrivateGPT instance serve multiple models while benefiting from a single document store.
