Vision Bridge

Use GLM-4.6V-Flash to convert images to text for non-vision AI models.

Problem

Many LLMs don't support image input. Vision Bridge solves this by using GLM-4.6V-Flash (free) as a vision intermediary.

How It Works

Image → GLM-4.6V-Flash → Text Description → Your Non-Vision Model

Installation

npm install -g vision-bridge

Setup

Set your ZhipuAI API key:

export ZHIPUAI_API_KEY="your-api-key"

Get API key: https://open.bigmodel.cn

Usage

Analyze Image

# From local file
vision-bridge analyze photo.jpg

# From URL
vision-bridge analyze https://example.com/image.png

# Custom prompt
vision-bridge analyze screenshot.png -p "What UI components are in this screenshot?"

# Stream output
vision-bridge analyze doc.jpg --stream

# Enable thinking mode for complex images
vision-bridge analyze chart.png --thinking

# Save to file
vision-bridge analyze receipt.jpg -o output.txt

OCR Mode

# Extract text from image
vision-bridge ocr document.jpg

# Save OCR result
vision-bridge ocr table.jpg -o table.md

Image2Prompt

# Generate AI art prompt from image
vision-bridge prompt artwork.jpg

Pipe to Other Models

# Use with any CLI model tool
vision-bridge analyze image.jpg | some-text-model --stdin

# Example workflow
vision-bridge analyze screenshot.png -o desc.txt
cat desc.txt | your-favorite-llm "Based on this UI description, generate the HTML/CSS code"
