Understanding Runway Gen-4.5 Cost: Plans, Credits, and API Rates
When diving into AI-generated video, understanding the token or credit economy of state-of-the-art models is essential to keeping your budget on track. Runway Gen-4.5 operates on a credit-based system, meaning what you pay depends entirely on whether you are using the web workspace app or building via the developer API.
1. In-App Web Generation Costs
Inside the Runway web studio, Gen-4.5 costs 12 credits per generated second of video.
- 5-second clip: 60 credits
- 10-second clip: 120 credits
Because generations can sometimes require multiple tries to nail down the exact motion or cinematic look you want, those credits can add up quickly.
2. Breakdown of Runway Subscription Tiers
Runway structures its web app around monthly or annual subscription tiers that refill your credit balance. Here is how the core tiers break down:
| Plan | Monthly Price | Monthly Credits | Approximate Gen-4.5 Output |
| :— | :— | :— | :— |
| Free | $0 | 125 (one-time grant) | ~10 seconds total |
| Standard | $15 ($12/mo billed yearly) | 625 credits | ~52 seconds |
| Pro | $35 ($28/mo billed yearly) | 2,250 credits | ~187 seconds |
| Max | $95 ($76/mo billed yearly) | 9,500 credits | ~791 seconds |
