SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires z-ai-web-dev-sdk, and includes scripts (resource) components.

What problem does it solve?

This Skill helps you build vision-capable chat workflows that can interpret images, answer questions about visual content, and support multimodal interactions without guessing at implementation details.

Core Features & Use Cases

  • Image Understanding: Analyze uploaded images or image URLs and generate descriptions, object detection-style summaries, and targeted answers.
  • Multimodal Chat: Combine text prompts with images, and extend the same pattern to video or document inputs where supported.
  • Operational Examples: Use it for product image analysis, OCR-style text extraction, visual comparison, accessibility alt text, content moderation, and chart or screenshot interpretation.

Quick Start

Ask the model to describe the provided image and answer one specific question about it using the vision chat workflow.

FAQPage Schema
How do I build a backend workflow for vision chat to analyze images and answer questions?

To build a backend vision chat workflow, you format image URLs or base64 inputs with the z-ai-web-dev-sdk to analyze visual content and generate targeted answers. This requires backend-only execution to process multimodal text and image inputs securely.

Can I use base64 image inputs for OCR and multimodal chat analysis?

Yes, you can process base64 image inputs for OCR and multimodal chat analysis. The workflow accepts both image URLs and base64 encoded data to extract text, interpret charts, and answer questions about the provided visual content.

What is multimodal image analysis used for in backend applications?

Multimodal image analysis is used for product analysis, OCR text extraction, accessibility alt text generation, content moderation, and chart reading. It combines text prompts with visual data to interpret screenshots and generate descriptive summaries.

Does the z-ai-web-dev-sdk support vision message formatting for backend execution?

Yes, the z-ai-web-dev-sdk supports vision message formatting for backend execution. It structures multimodal messages containing text and images to enable visual question answering and image understanding workflows.

What is the best way to extract text from an image URL using a multimodal assistant?

The best way to extract text from an image URL is passing it into a vision chat workflow formatted with the z-ai-web-dev-sdk. The multimodal assistant analyzes the visual content and returns accurate OCR-style text extraction results.

Are there limitations to running multimodal chat workflows on the backend?

A key limitation is that multimodal chat workflows require backend-only execution and cannot run directly in the browser. You must also properly format image URLs or base64 strings using the z-ai-web-dev-sdk to avoid processing errors.
