FAQPage Schema
How do I generate descriptive text from an image URL in a backend service?

To generate descriptive text from an image URL in a backend service, use the z-ai-web-dev-sdk createVision API to process the URL and send text prompts for conversational image analysis.

Can I use base64-encoded images for vision chat analysis?

Yes, you can use base64-encoded images for vision chat analysis by passing the base64 string directly into the multimodal chat interface alongside your text prompt.

Does multimodal image analysis support multi-turn conversations?

Multimodal image analysis supports multi-turn conversations, allowing you to combine text prompts with image inputs for rich, contextual follow-up questions about the visual content.

How do I set up a backend vision chat using z-ai-web-dev-sdk?

To set up a backend vision chat, install the z-ai-web-dev-sdk, implement the createVision API, and reference the sample scripts provided in the scripts directory for integration guidance.

What are common use cases for AI image description in backend applications?

Common use cases for AI image description include building applications that automatically describe product photos, summarize complex diagrams, or perform question answering on image content.

Does multimodal vision chat require a specific deployment environment?

Multimodal vision chat requires backend deployment to securely run the z-ai-web-dev-sdk and process image URLs or base64 inputs without exposing API keys to the frontend.
