Example Code

            const tool = new DallEAPIWrapper({
                n: 1, // Default
                model: "dall-e-3", // Default
                apiKey: process.env.OPENAI_API_KEY, // Default
                size: "512x512", // Choose the desired size
              });
              
              const imageURL = await tool.invoke(prompt);

Description

I've tried to add image size to the DalleAPIWrapper, but I get this error:

Hello, @joshpopelka20gmail! I'm here to assist you with your LangChain-related query. Let's work together to resolve the issue you've encountered.

The error "The size is not supported by this model" occurs because the size "512x512" is not supported by the DALL·E-3 model. For DALL·E-3, the supported sizes are "1024x1024", "1792x1024", or "1024x1792" ^[1].

To resolve this, you should change the size parameter in your DallEAPIWrapper configuration to one of the supported sizes for DALL·E-3. For example:

const tool = new DallEAPIWrapper({
  n: 1, // Default
  model: "dall-e-3", // Default
  apiKey: process.env.OPENAI_API_KEY, // Default
  size: "1024x1024", // Use a supported size for DALL·E-3
});

This should resolve the error and allow you to generate images with the DALL·E-3 model.
