This commit introduces a new "OpenAI Compatible" provider, allowing users to connect to any service that implements the OpenAI API specification.
Previously, users were limited to the pre-defined list of providers. With the proliferation of many new AI services and local models (like LM Studio, vLLM, etc.) that expose an OpenAI-compatible endpoint, it has become impractical to add and maintain a separate integration for each one.
This new generic provider solves that problem by offering a single, flexible solution. It clarifies the user's choice by separating the official OpenAI service from other compatible alternatives, improving the overall user experience.
Closes#401, #388
