ComfyUI Node: Image With Prompt

Image With Prompt:

The KepOpenAI_ImageWithPrompt node is designed to generate high-quality textual descriptions or captions for images using OpenAI's advanced language models. This node leverages the capabilities of the GPT-4-vision-preview model to analyze an image and produce a detailed and contextually relevant caption based on a provided prompt. The primary benefit of this node is its ability to create rich, descriptive text that highlights the most important aspects of an image, making it an invaluable tool for AI artists who need to generate captions, descriptions, or other textual content related to visual media. By integrating image analysis with natural language processing, this node helps streamline the creative process and enhances the quality of the generated content.

Image With Prompt Input Parameters:

Image

This parameter expects an image in the form of a tensor. The image serves as the primary visual input that the node will analyze to generate a caption. The quality and content of the image directly impact the relevance and accuracy of the generated text.

prompt

This is a string parameter that allows you to provide a textual prompt to guide the caption generation process. The prompt can be multiline and should describe the desired focus of the caption. For example, you can instruct the model to emphasize certain aspects of the image or apply weights to specific words or phrases using the format (word or phrase:weight). The default prompt is Generate a high quality caption for the image. The most important aspects of the image should be described first. If needed, weights can be applied to the caption in the following format: '(word or phrase:weight)', where the weight should be a float less than 2.

max_tokens

This integer parameter specifies the maximum number of tokens (words and punctuation) that the generated caption can contain. The range for this parameter is from 1 to 2048, with a default value of 77. Adjusting this value allows you to control the length and detail of the generated text.

Image With Prompt Output Parameters:

STRING

The output of this node is a string that contains the generated caption or description for the provided image. This text is crafted based on the input image and the provided prompt, aiming to deliver a high-quality and contextually relevant description that captures the essence of the image.

Image With Prompt Usage Tips:

• Ensure that the input image is clear and of high quality to improve the accuracy and relevance of the generated caption.
• Use specific and detailed prompts to guide the model towards generating the desired type of description. For example, if you want the caption to focus on certain elements of the image, mention them explicitly in the prompt.
• Adjust the max_tokens parameter based on the level of detail you need in the caption. For shorter, more concise descriptions, use a lower value; for more detailed captions, increase the value.

Image With Prompt Common Errors and Solutions:

No response from OpenAI API

• Explanation: This error occurs when the OpenAI API does not return any response choices.
• Solution: Ensure that your API key is valid and that you have not exceeded your usage limits. Check your internet connection and try again. If the problem persists, contact OpenAI support for further assistance.

Invalid image format

• Explanation: This error occurs if the input image is not in the expected tensor format.
• Solution: Verify that the image is correctly formatted as a tensor before passing it to the node. Use appropriate image processing libraries to convert the image to the required format.

Prompt too long

• Explanation: This error occurs if the provided prompt exceeds the maximum allowed length.
• Solution: Shorten the prompt to fit within the allowed length. Ensure that the prompt is concise and focused on the key aspects you want the model to consider.
