<Info>
  Runway Gen 4 Turbo is the speed-optimized version of [Runway 4.5](/ai-models/video/runway-4-5). Use Gen 4 Turbo for rapid iteration and drafts; use Runway 4.5 for final-quality production output.
</Info>

## Speed at every stage

Runway Gen 4 Turbo, released April 2025, is built for iteration speed. At 5× faster than standard Runway Gen 4 with a reduced credit cost, it makes rapid visual exploration practical — generate 10 different directions for a scene in the time it would take to produce 2 with the full-quality model. Supports 5 or 10 second clip lengths.

Image-to-video is a particular strength: uploading a reference image and animating it with a motion prompt produces results in approximately 30 seconds, making Turbo ideal for quick concepting, client previews, and pipeline drafts.

## Prompting tips

* **Use Turbo for direction exploration** — Generate 5–10 variations of a scene quickly, pick the best direction, then render the final in [Runway 4.5](/ai-models/video/runway-4-5).
* **Image prompts + motion description** — Upload a product image and write "the camera slowly circles clockwise around the object" for fast product video.
* **Keep prompts direct** — For rapid iteration, focused prompts ("wide shot, camera pans right, golden hour lighting") produce faster and more predictable results than long descriptive paragraphs.

### Example prompts

> A car drives along a coastal highway at sunset. Tracking shot from the side, maintaining pace with the car. Warm light, slight motion blur. 10 seconds.

> A coffee shop interior in the morning. Camera slowly drifts forward through the space, customers in background, warm light through windows. Handheld feel.

<Tip>
  Run Runway Gen 4 Turbo first to validate your direction quickly, then switch to [Runway 4.5](/ai-models/video/runway-4-5) for the final render. The Turbo model's output is representative enough to make confident decisions about composition, camera, and pacing.
