What problem does it solve? Building applications that understand images requires wiring up multimodal AI APIs, handling image formats, and managing conversation state. This Skill provides ready-to-use patterns for adding vision chat capabilities to backend applications using the z-ai-web-dev-sdk. ## Core Features & Use Cases - Image Analysis via SDK or CLI: Analyze images from URLs, local files, or base64 data using the createVision API or the z-ai vision CLI command. - Multimodal Content Support: Combine text with images, videos, and documents (image_url, video_url, file_url) in a single message, including multi-image comparisons. - Conversational Vision Sessions: Maintain multi-turn conversations about images with follow-up questions, plus structured outputs for classification, tagging, and OCR text extraction. - Use Case: Build an Express.js endpoint that accepts an image URL and a question, then returns a detailed AI-generated description for e-commerce product analysis or automated alt-text generation. ## Quick Start Ask the AI to analyze an image by running the z-ai vision CLI with a prompt and image URL, or implement a backend endpoint using the createVision example from this Skill.
