/**
|
|
* Extracts a valid OpenAI baseURL from a given string, matching "url/v1," followed by an optional suffix.
|
|
* The suffix can be one of several predefined values (e.g., 'openai', 'azure-openai', etc.),
|
|
* accommodating different proxy patterns like Cloudflare, LiteLLM, etc.
|
|
* Returns the original URL if no valid pattern is found.
|
|
*
|
|
* Examples:
|
|
* - `https://open.ai/v1/chat` -> `https://open.ai/v1`
|
|
* - `https://open.ai/v1/chat/completions` -> `https://open.ai/v1`
|
|
* - `https://gateway.ai.cloudflare.com/v1/account/gateway/azure-openai/completions` -> `https://gateway.ai.cloudflare.com/v1/account/gateway/azure-openai`
|
|
* - `https://open.ai/v1/hi/openai` -> `https://open.ai/v1/hi/openai`
|
|
* - `https://api.example.com/v1/replicate` -> `https://api.example.com/v1/replicate`
|
|
*
|
|
* @param {string} url - The URL to be processed.
|
|
* @returns {string | undefined} The matched pattern or input if no match is found.
