            top_p: Nucleus sampling threshold (0~1).
            top_k: Top-K sampling (0 to disable). vLLM/SGLang extra param.
            min_p: Minimum probability threshold. vLLM/SGLang extra param.
            presence_penalty: Penalize tokens already present in the output.
            repetition_penalty: Penalize repeated tokens. vLLM/SGLang extra param.
            api_base: API base URL (full URL to chat/completions endpoint).
            port: Port number for local deployments.
            retry: Number of retry attempts on API failure.
            wait: Max wait time between retries (seconds).
            timeout: Request timeout as (connect_timeout, read_timeout) tuple.
            max_tokens: Maximum tokens in response.
            thread_num: Maximum number of concurrent requests (semaphore limit).
            return_dict: Whether to parse response as dict via load_str_to_dict.
            logger: Logger instance.
            max_connections: Max TCP connections in the pool. Defaults to
                min(thread_num, 16384).
            enable_thinking: Whether to enable thinking mode for models that support it
                (e.g., Qwen3 on vLLM/SGLang). Default False.
