Breaking Down the Cost of Runway Gen-4.5: What Creators Need to Know

Artificial intelligence video generation has crossed a major threshold. With the release of Runway Gen-4.5, the fidelity, cinematic coherence, and prompt adherence of AI-generated video have reached new heights. But professional-grade capability comes with a price tag.

If you are trying to figure out how much Runway Gen-4.5 costs, the answer depends entirely on how you plan to use it—whether through Runway’s web application workspace or via developer APIs.

1. The Core Metric: Cost Per Second

In the Runway ecosystem, Gen-4.5 is a flagship, high-compute model. It operates on a credit-based consumption model.

• App Consumption Rate: Gen-4.5 typically consumes 12 credits per second of generated video (though some configurations or master formats like ProRes/PNG sequences feature surcharges up to an extra 5 credits per second).
• The Breakdown:
  • A standard 2-second clip costs 24 credits.
  • A standard 5-second clip costs 60 credits.
  • A maximum-length 10-second clip costs 120 credits.

2. Runway Web App Subscription Tiers

To use Gen-4.5 in the web studio, you need an active paid subscription. The Free tier generally does not unlock full access to top-tier flagship models. Runway offers three primary creator tiers (with 20% discounts for annual commitments):

| Plan | Monthly Price (Month-to-Month) | Annual Equivalent (Billed Annually) | Monthly Credits Included | Approximate 5-Second Gen-4.5 Clips* |
| :— | :— | :— | :— | :— |
| Standard | $15 / month | $12 / month ($144/yr) | 625 credits | ~10 clips |
| Pro | $35 / month | $28 / month ($336/yr) | 2,250 credits | ~37 clips |
| Max / Unlimited | $95 / month | $76 / month ($912/yr) | 9,500 credits (or 2,250 + Explore Mode) | ~158 clips |
