# Generate images Use `executors/generate-image/generate-image.mjs` for text-to-image and reference-image editing. It is a repository-owned, zero-dependency Node.js client.

For JSONL batch generation, put one job per line with `prompt` or `prompt_file`, `out`, and optional `model`, `refs`, `size`, or `quality`: ```bash node executors/generate-image/generate-image.mjs \ --batch <jobs.jsonl> --out-dir <directory> --concurrency 3 ``` Read `GEMINI_API_KEY` or `OPENAI_API_KEY` from the process environment.
