FAQPage Schema
How do I add image analysis to a backend chat application?

You can enable vision-based image understanding in chat conversations by passing single or multiple image URLs or base64 data to the backend z-ai-web-dev-sdk.

Can I analyze multiple images in a single chat prompt?

Yes, vision-based multimodal chat supports analyzing and reasoning about single or multiple images within the same conversation to generate contextual descriptions and visual QA responses.

Does vision-based image understanding work with base64 data instead of image URLs?

Yes, the backend workflow accepts both image URLs and base64 data for vision chat sessions, allowing flexible multimodal image processing without requiring public URL access.

What are common use cases for multimodal image analysis in backend workflows?

Multimodal image analysis supports generating product descriptions, creating accessibility alt text, and performing visual question answering to reason about visual content server-side.

Do I need the z-ai-web-dev-sdk to run image analysis on the backend?

Yes, the z-ai-web-dev-sdk is required as a backend dependency to securely process image inputs and construct vision prompts for multimodal chat responses.

How are error scenarios handled during multimodal vision chat processing?

The backend workflow provides specific examples for handling error scenarios during vision chat processing, ensuring robust management of image input failures and response generation issues.
