input_format_error
Invalid chat format: Unexpected keys found in message content.
This error has been identified and solved.
Reason
The 400 Bad Request error with the message "Invalid chat format. Unexpected keys in a message content image dict" in the OpenAI API is likely due to the following reasons:
Incorrect Request Format
The request payload does not match the expected format for the API endpoint. Specifically, the content field in the message object may contain unexpected or unsupported keys, which the API does not recognize.
Invalid Chat Format
The API expects a specific structure for chat messages, particularly when dealing with models like gpt-4-vision-preview that support both text and images. The format may be incorrect, such as including invalid or unexpected types in the content array.
Misalignment with Model Expectations
The request may not adhere to the specific requirements of the model being used. For example, the gpt-4-vision-preview model has particular expectations for how text and image data should be formatted and included in the request payload.
Solution
To fix the 400 Bad Request error due to an "Invalid chat format" in the OpenAI API, you need to ensure the following:
Validate the message format: Ensure that the message structure complies with the expected JSON object format for the
gpt-4-vision-previewmodel.Correct content fields: Make sure the
contentfield in the message object only contains supported keys, such astextorimage_url, and that these fields are correctly formatted.Remove unexpected parameters: Verify that there are no extra or unsupported parameters in the request payload.
Properly include image data: If sending image data, ensure it is either provided as a valid URL or correctly encoded and structured according to the model's requirements.
Check the model's YAML configuration: Refer to the model's YAML configuration file to ensure all parameters and message formats align with the model's expectations.
By ensuring these points, you can correct the format issues causing the error.
