Your Question

I cannot use the image generation model, even though I have the corresponding model's API key, it still doesn't work. I found that the issue lies in the preview, where most models' API endpoints are automatically appended with "chat/completions", while images require adding "image/generations" after the API endpoint. Due to this automatically added suffix "chat/completions", I am unable to call the image model, while other language models work fine.
