Enhancement: allow users to set 3rd party OpenAI api URL

Feature request: allow users to set 3rd party OpenAI api URL. Many websites provide open source models compatible with OpenAI. Above the OpenAI key parameter, please add one for the URL.

Any particular URL / API you want supported? Some of them work quite differently, particularly around authentication and what's in the auth headers.

Thanks for the quick response! Many inference servers like Ollama and LM Studio expose OpenAI compatible end-points. They can run DeepSeek, Qwen, GLM and other models.
