openai-image-cli

A command-line interface tool for generating images using OpenAI's DALL-E models (dall-e-3, dall-e-2, gpt-image, and gpt-image-mini).

Features

• Generate images using DALL-E 3, DALL-E 2, GPT-Image, or GPT-Image Mini
• Customizable image sizes
• Support for multiple image generation (dall-e-2 only)
• Automatic image download and saving
• Simple command-line interface
• Written in TypeScript for type safety

Installation

Using npx (Recommended)

Run directly without installation:

npx openai-image-cli "A sunset over mountains"

Global Installation

npm install -g openai-image-cli

Local Development

• Clone the repository:

git clone https://github.com/lpenguin/openai-image-cli.git
cd openai-image-cli

• Install dependencies:

npm install

• Build the project:

npm run build

• Set up your OpenAI API key:

export OPENAI_API_KEY=your-api-key-here

Usage

Basic Usage

npx openai-image-cli "A sunset over mountains"
# or if installed globally
openai-image "A sunset over mountains"
# or if running locally
node dist/index.js "A sunset over mountains"

With Options

npx openai-image-cli --prompt "A cat playing piano" --size 1024x1024 --n 1

Using Different Models

# DALL-E 2 with multiple images
npx openai-image-cli "Abstract art" --model dall-e-2 --size 512x512 --n 2

# GPT-Image
npx openai-image-cli "Modern design" --model gpt-image --size 1024x1024

# GPT-Image Mini
npx openai-image-cli "Quick sketch" --model gpt-image-mini

Command-Line Options

• --prompt <text> - Image generation prompt (required if not using positional argument or --prompt-file)
• --prompt-file <path> - Path to file containing the prompt (alternative to --prompt)
• --size <size> - Image size (default: 1024x1024)
  • DALL-E 3 sizes: 1024x1024, 1024x1792, 1792x1024
  • DALL-E 2 sizes: 256x256, 512x512, 1024x1024
  • GPT-Image sizes: 1024x1024, 1024x1792, 1792x1024
  • GPT-Image Mini sizes: 1024x1024, 1024x1792, 1792x1024
• --n <number> - Number of images to generate (default: 1)
  • Note: DALL-E 3, GPT-Image, and GPT-Image Mini only support n=1
• --model <model> - Model to use: dall-e-3, dall-e-2, gpt-image, or gpt-image-mini (default: dall-e-3)
• --help, -h - Show help message

Environment Variables

• OPENAI_API_KEY (required) - Your OpenAI API key

Examples

Generate a single image with DALL-E 3:

export OPENAI_API_KEY=sk-...
npx openai-image-cli "A futuristic city at night"

Generate an image using a prompt from a file:

npx openai-image-cli --prompt-file my-prompt.txt --model dall-e-3

Generate multiple images with DALL-E 2:

npx openai-image-cli "A cute robot" --model dall-e-2 --size 512x512 --n 3

Generate a wide image with GPT-Image:

npx openai-image-cli "A panoramic landscape" --model gpt-image --size 1792x1024

Use GPT-Image Mini for faster generation:

npx openai-image-cli "A simple sketch" --model gpt-image-mini

Output

Generated images are automatically downloaded and saved to the current directory with filenames like:

• generated_image_<timestamp>_1.png
• generated_image_<timestamp>_2.png

Development

Build the project:

npm run build

The TypeScript source is in src/ and compiles to dist/.
