Runway Gen-4.5 pricing and limits
Runway Gen-4.5 on Runway Dev. Status: available. Checked 2026-10-07 against the official Runway Dev source. This is the platform price shown, not a universal model price across resellers.
Price and calculation
Billing: API credits. Base resolution: base output. $0.120 per output second. Runway Dev API credits; 12 credits/s × $0.01/credit. Pro formats cost extra.
Formula: 12 credits/output second × $0.01/credit = $0.120/second. Per clip: max(duration × 12 credits, 0 minimum credits) × $0.01. Multiply by monthly clip count. The minimum and any input/reference charges can change the effective rate.
Example: 100 clips × 5s at the base setting = $60.00, before extras.
