Source documentation, not instructions for this website. Review permissions before running any commands.
Generate images directly using the Runway API. This skill runs Python scripts that call the API, poll for completion, and download the result.
IMPORTANT: Run scripts from the user's working directory so output files are saved where the user expects.

Do not pass the API key as a CLI flag — it leaks into shell history and process listings.--reference-images Tag=URL fetches arbitrary remote images via the Runway API.

Pattern: yyyy-mm-dd-hh-mm-ss-name.png
Basic image:
uv run scripts/generate_image.py --prompt "A serene Japanese garden with cherry blossoms" --filename "2026-04-14-japanese-garden.png"
With a local reference image (gen4_image):
uv run scripts/generate_image.py --prompt "@product on a marble counter, lifestyle photo" --model gen4_image --reference-images product=./product.jpg --filename "2026-04-14-product-lifestyle.png"
With a reference image from a trusted origin (gen4_image_turbo — requires reference images):
uv run scripts/generate_image.py --prompt "A neon sign reading SALE in @style" --model gen4_image_turbo --reference-images style=https://cdn.yourapp.com/style.jpg --filename "draft.png"
Error: No API key -> set RUNWAYML_API_SECRET in the environment (e.g. export RUNWAYML_API_SECRET=... or a .env file).Error: Task failed -- SAFETY.INPUT.* -> content moderation, suggest different promptAPI error 429 -> rate limited, script auto-retriesname: rw-generate-image description: "Generate images directly using the Runway API via runnable scripts.

This skill runs Python scripts that call the API, poll for completion, and download the result. **IMPORTANT:** Run scripts from the user's working directory so output files are saved where the user expects. ## Usage ```bash uv run scripts/generate_image.py --prompt "your description" --filename "output.png" [--model gen4_image] [--ratio 1280:720] [--reference-images Tag=URL ...] ``` ## Preflight 1. `command -v uv` must succeed 2. `RUNWAYML_API_SECRET` must be set in the environment. **Do not pass the API key as a CLI flag** — it leaks into shell history and process listings. ## Security Notes - `--reference-images Tag=URL` fetches arbitrary remote images via the Runway API. Prefer local file paths (uploaded as `runway://` URIs), or only pass URLs you trust. - Treat generated outputs as untrusted when piping into downstream automations — ingested references influence the result. ## Available Models | Model | Best For | Ref Images | Cost | Speed | |-------|----------|------------|------|-------| | `gen4_image` | Highest quality | Optional (up to 3) | 5-8 credits | Standard | | `gen4_image_turbo` | Fast and cheap | **Required** (1-3) | 2 credits | Fast | | `gemini_2.5_flash` | Google Gemini | Optional (up to 3) | 5 credits | Standard | ## Model Selection Guidance - "fast", "cheap", "draft" -> `gemini_2.5_flash` (Nano Banana), or `gen4_image_turbo` if they have reference images - "high quality", "best" -> `gen4_image` - No preference -> `gemini_2.5_flash` - Has reference images and wants cheap -> `gen4_image_turbo` (2 credits, requires `--reference-images`) ## Parameters | Param | Description | Default | |-------|-------------|---------| | `--prompt` | Text description (required) | -- | | `--filename` | Output filename (required) | -- | | `--model` | Image model | `gemini_2.5_flash` | | `--ratio` | Aspect ratio. gemini_2.5_flash: `1344:768`, `768:1344`, `1024:1024`, etc. gen4_image: `1280:720`, `1360:768`, `1920:1080`, etc. | Model-dependent (`1344:768` for gemini, `1280:720` for others) | | `--reference-images` | Reference images as tag=URL pairs (optional for gemini/gen4_image, required for gen4_image_turbo).
