The total number of tokens exceeds the model's maximum context length. Please reduce the length of your messages or functions.

To fix the 400 status error due to exceeding the maximum context length, you need to reduce the overall token count of your request. Here are some steps to achieve this:

Break down the input into chunks:

• Divide your long text into smaller sections that fit within the 128,000 token limit.

• Send these chunks separately, instructing the model to wait for all parts before generating the response.

Optimize the context:

• Remove any unnecessary context or instructions.

• Use text preprocessing techniques to reduce the size of your input without losing its meaning.

Use the messages array efficiently:

• Ensure each message in the messages array is below the token limit.

• If possible, move standard context or instructions to a separate setup, such as under "instructions" on the OpenAI website, to avoid including them in every API request.

Control the response length:

• If applicable, specify the desired response length in your prompt to prevent the model from generating excessively long responses.
