OpenAI Image Gen

This skill uses aivault to keep your OpenAI API key safe. The script only invokes openai/image-generation.

Setup

Install aivault if it is not already available:

curl -fsSL https://aivault.moldable.sh/install.sh | sh

Store your OpenAI API key in aivault. The credential and all openai/* capabilities are auto-provisioned from the built-in registry.

aivault secrets create --name OPENAI_API_KEY --value "sk-..." --scope global

This skill uses openai/image-generation.

Quick start

npx -y tsx {baseDir}/scripts/generate.ts --count 8

Common examples

npx -y tsx {baseDir}/scripts/generate.ts --prompt "ultra-detailed studio photo of a lobster astronaut" --count 4
npx -y tsx {baseDir}/scripts/generate.ts --model gpt-image-1 --size 1536x1024 --quality high --out-dir ./out/images
npx -y tsx {baseDir}/scripts/generate.ts --model dall-e-3 --style vivid --prompt "serene mountain landscape" --count 1
npx -y tsx {baseDir}/scripts/generate.ts --json

Output

• Images written to --out-dir (default: ./tmp/openai-image-gen-<timestamp>).
• prompts.json mapping prompt to filename.
• index.html thumbnail gallery.
