Runway Gen 4 Turbo is the speed-optimized version of Runway 4.5. Use Gen 4 Turbo for rapid iteration and drafts; use Runway 4.5 for final-quality production output.
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. 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.Capabilities
5× faster generation
Generates video 5× faster than standard Runway Gen 4 — enables rapid creative exploration and faster production pipelines.
Strong image-to-video
Excellent image animation performance — strong visual fidelity when animating a reference starting frame with a motion prompt.
10-second clips
Up to 10 seconds per generation — sufficient for most social media clips, brand content, and narrative sequences.
Multiple aspect ratios
Supports 16:9, 9:16, 1:1, 4:3, 3:4, and 21:9 for all platform formats.
Camera and subject control
Responsive to cinematographic prompting — camera movements, subject behavior, and scene composition all follow prompt instructions accurately.
Optimized transformer architecture
Hardware-accelerated Transformer architecture with the same spatial coherence principles as the full-quality model, optimized for speed.

Describe motion and camera
Include explicit camera direction and subject movement in your prompt for the most controlled results.
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.
- 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.
