+### 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-2.5-Flash, are exceptions
+#### OpenAI's new API utilizes max_completion_tokens instead of max_tokens
