2. Temperature

The temperature parameter controls the randomness of the model’s output. Higher values like 0.8 make the output more random and creative, while lower values like 0.2 make it more focused and deterministic. Experimenting with different temperature values can help you strike the right balance between creativity and control.

3. Max Tokens

The max tokens parameter allows you to limit the length of the response generated by the model. By setting a specific value for max tokens, you can ensure that the response stays within a desired length. However, be cautious not to set it too low, as it may result in incomplete or cut-off responses.

4. Top P (Nucleus) Sampling

Top P sampling, also known as nucleus sampling, allows you to control the diversity of the generated responses. Instead of sampling from the entire probability distribution, you sample from the smallest possible set of tokens whose cumulative probability exceeds a certain threshold (e.g., 0.9). This approach ensures that the model generates diverse responses while still maintaining a level of coherence.

5. User Messages and Assistant’s Previous Responses

When interacting with the ChatGPT-4 API, you can include both user messages and the assistant’s previous responses to provide context and maintain the conversation’s flow. Including the conversation history allows the model to have a better understanding of the dialogue’s context and generate more accurate and relevant responses.

6. Timeouts and Pagination

If you have long conversations or need to paginate through multiple API calls, you can use the timeout and pagination features. The timeout parameter allows you to specify the maximum time in seconds that the API call should take. If the response is not received within the specified timeout, you can retry the request. Pagination can be achieved by specifying the page size and using the “offset” parameter to retrieve subsequent pages of the conversation.

7. Fine-tuning and Customization

If you have specific domain requirements or want to improve the model’s performance, you can consider fine-tuning the base models provided by OpenAI.
