Can I generate images from text?

Yes! Use the `generate_image` tool with Stable Diffusion models. Provide a descriptive prompt and optionally specify size (e.g., '1024x1024').

Can I ask questions about an image?

Yes! Use `visual_question_answering` with a public image URL and your question. The AI will analyze and respond with details about the image.

Does it work with scanned documents?

Yes! Use `document_qa` to extract information from scanned documents, forms, receipts, and other image-based documents.

What image sizes can I generate?

Stable Diffusion models support various sizes including 512x512, 768x768, and 1024x1024. Higher resolutions produce more detailed images but take longer to generate.
