The request exceeds the model's maximum context length. Please reduce the length of the messages or completion.

To fix the 400 status error due to exceeding the maximum context length in the Azure OpenAI API, you need to reduce the total number of tokens in your request. Here are the steps to achieve this:

• Reduce the length of the messages: Trim down the context or messages you are passing to fit within the allowed token limit.

• Reduce the completion tokens: Lower the max_tokens or max_completion_tokens parameter to a value that keeps the total tokens under the model's limit.

• Break the request into smaller chunks: If necessary, split your request into multiple smaller requests to stay within the token limits.

• Optimize your prompt: Consider moving some context to a less token-intensive part of the API, such as using the "system prompt" or "instructions" if available.

By adjusting these parameters, you can ensure your requests comply with the model's token limits and avoid the 400 error.
