 ### OpenAI Compatible API Specific Parameters
 ### Set the max_tokens to mitigate endless output of some LLM (less than LLM_TIMEOUT * llm_output_tokens/second, i.e. 9000 = 180s * 50 tokens/s)
 ### Typically, max_tokens does not include prompt content, though some models, such as Gemini Models, are exceptions
+### For vLLM/SGLang doployed models, or most of OpenAI compatible API provider
