 OpenAI supports a wide range of programming languages for algorithm generation. Users can specify their preferred programming language when requesting algorithmic posts. Commonly supported languages include Python, Java, JavaScript, C++, and more.
 
+### Q5: How can I set the maximum tokens for the OpenAI API when making requests?
+
+Controlling the maximum algorithmic email length can be achieved by setting the maximum number of tokens allowed in the generated text, namely [`max_tokens`](https://github.com/coder-inbox/code-inbox-server/blob/main/src/utils/openai_api.py#L41). Tokens are units of text that can be as short as one character or as long as one word. To control email length, set the parameter `max_tokens` to a value that ensures your email content remains within the token limit. For example, if the token limit is 1024 tokens, you might set `max_tokens` to 1024.
