Problem Description
I am using Azure OpenAI for all models. With the GPT-image-1 and Dall-e-3 available on Azure OpenAI, we want to support image generation through azure. However, any attempts to configure the image generation with azure fails.
I have attempted to use the Azure OpenAI API URL instead of the default OpenAI URL and tested multiple options for the URL:
I wanted to test it with Dall-e-3 first, so my default model is currently configured with "dall-e-3". Image size is 1024x1024. Steps is set to 1, but I've tried 10, 50, 100 too.
I'm using 4o for the chat.
While Open WebUI saves and enables the feature correctly, I get this response:
Clicking on the "Generate image" button, results in a popup "Error: Resource not found":
Desired Solution you'd like
I'd like to just be able to to use Azure OpenAI for image generation. Just like for the chat models. Thank you!
