'$.messages' exceeds the maximum length of 2048 items. Please reduce the number of items in the messages.

To fix the 400 status error due to the context length exceeding the maximum allowed, you need to adjust the length of your request. Here are the steps to resolve this issue:

• Reduce the length of the messages: Trim down the conversation context or the new prompt to fit within the allowed token limit.

• Break the context into smaller chunks: If the context is too long, consider breaking it into multiple requests, each within the allowed token limit.

• Optimize the prompt: Remove any unnecessary parts of the prompt or context to minimize the token count.

• Use a different model: If possible, switch to a model with a higher context length limit, though this may not always be feasible depending on your requirements.

By implementing these adjustments, you can ensure your requests comply with the API's token limits.
