unsupported_content_type_error
Invalid content type: image URLs are only supported by certain models.
This error has been identified and solved.
Reason
The error "Invalid content type. image_url is only supported by certain models" with a 400 status code in the OpenAI API occurs because the model you are using does not support the image_url parameter. Here are the key points:
Model Limitations
The
image_urlparameter is only compatible with specific models that are designed to handle image inputs, which is not the case for many of the current OpenAI models like GPT-4, GPT-4o-mini, etc..
Model Capabilities
Models such as GPT-4 and its variants are primarily text-based language models and do not have the capability to analyze images. The error indicates that the model you are using is not equipped to process image URLs.
Intermittent Errors
Although the error might occur intermittently, it is consistent with the model's limitations and not a transient issue with the API request itself.
Solution
To fix the "Invalid content type. image_url is only supported by certain models" error, you need to ensure you are using a model that supports image inputs. Here are the steps to resolve the issue:
Use a compatible model: Switch to a model that is designed to handle image inputs, such as the GPT-4-Vision or other vision-enabled models.
Check model documentation: Verify the capabilities of the model you are using and ensure it supports image URLs.
Adjust your API request: If you are using a text-only model, remove the
image_urlparameter from your request or modify it to comply with the model's supported content types.
By making these adjustments, you can avoid the 400 error related to invalid content types.
