Runway Gen-4 pricing: the short answer
In Runway’s web app, Gen-4 video costs 12 credits per second: 60 credits for a 5-second generation or 120 credits for 10 seconds. Gen-4 requires an input image. Gen-4 Turbo is a separate option at 5 credits per second. (Runway’s Gen-4 guide)
Runway’s pricing page displays Standard at $15/month or $12/month billed annually, Pro at $35/month or $28/month billed annually, and Max at $95/month or $76/month billed annually. Their monthly allowances are 625, 2,250, and 9,500 credits, respectively. The page describes these plans as providing access to all AI video and image models; Gen-4’s guide lists web and iOS availability. The pricing page does not label the prices as per-user or per-account, so confirm the charge basis at checkout. Annual prices are monthly equivalents with annual billing, not month-to-month rates. (Runway pricing; Gen-4 guide)
For API use, the documented Gen-4-family option is Gen-4 Turbo, not standard Gen-4: Runway Dev lists gen4_turbo at $0.05 per second. A 5-second Turbo generation is $0.25 before any applicable tax. The API reference accepts gen4_turbo at POST /v1/image_to_video; the listed accepted model IDs do not include standard Gen-4. So the official API docs establish Turbo’s route and rate, but do not establish a standard Gen-4 API route or price. (Runway Dev model list; API reference)
| Route and model | Usage cost | Example |
|---|---|---|
| Runway app: Gen-4 video | 12 app credits/second | 60 credits for 5 seconds; 120 for 10 seconds |
| Runway app: Gen-4 Turbo video | 5 app credits/second | 25 credits for 5 seconds; 50 for 10 seconds |
| Runway Dev API: Gen-4 Turbo | $0.05/second | $0.25 for 5 seconds; $0.50 for 10 seconds |
| Runway Dev API: standard Gen-4 | No standard Gen-4 model ID or rate established in the API docs cited here | Don’t assume app availability means API availability |
App-plan credits and Runway Dev project credits are separate pricing contexts. Runway Dev says project credits cost $0.01 each; use the API’s published dollar rate for API estimates rather than converting an app subscription’s monthly allowance into an API budget. Sales tax may apply depending on location. (Runway Dev pricing)
App plan costs and a Gen-4 budget
The following clip counts are arithmetic estimates using each plan’s published monthly credit allowance and Gen-4’s 60-credit cost for a 5-second generation. They assume every credit is spent on Gen-4 and round down; they are not guaranteed finished-shot counts. (Runway pricing; Gen-4 guide)
| Plan | Month-to-month price | Monthly equivalent with annual billing | Credits/month | 5-second Gen-4 clips if all credits go to Gen-4* |
|---|---|---|---|---|
| Standard | $15 | $12 | 625 | 10 |
| Pro | $35 | $28 | 2,250 | 37 |
| Max | $95 | $76 | 9,500 | 158 |
*Calculation: monthly credits ÷ 60 credits per 5-second clip, rounded down. Other models and tools, longer generations, and retries reduce the number of clips the allowance can cover. A 10-second Gen-4 generation costs twice as much as a 5-second one. (Gen-4 guide)
Example: Ten 5-second Gen-4 generations use 10 × 60 = 600 credits. That fits within Standard’s 625-credit monthly allowance, leaving 25 credits. This is a generation budget, not a promise of ten finished shots: each new generation or retry also uses credits. Standard’s displayed annual-billing rate is $12/month, compared with $15/month month-to-month. The pricing page displays plan prices without specifying whether they are per user or per account; check the purchase screen for the billing basis.
For cheaper iteration, Gen-4 Turbo uses 25 credits for a 5-second generation, compared with 60 for Gen-4. Runway recommends trying Turbo first and switching to Gen-4 if Turbo does not meet the desired result. Both require an input image. (Runway’s Gen-4 guide)
Gen-4 Turbo API pricing and route
Runway Dev’s API reference documents image-to-video at POST /v1/image_to_video and accepts gen4_turbo as a model ID. It requires an API key using Bearer authorization. Runway Dev’s model list describes Gen-4 Turbo as image-to-video and prices it at $0.05 per second. The cited model list and endpoint’s accepted IDs do not establish a standard Gen-4 API model or rate. (Runway Dev API reference; available models)
API budget example: 20 five-second Gen-4 Turbo generations × 5 seconds × $0.05/second = $5 in generation charges, before any applicable tax. Runway Dev’s published pricing says sales tax may apply depending on location. This example estimates generation charges only; it is not the same as the app-plan subscription calculation. (Runway Dev pricing)
Don’t confuse Gen-4 with other Runway models
- Gen-4 video: 12 app credits per second; requires an input image.
- Gen-4 Turbo video: 5 app credits per second in the app; the documented Runway Dev API model is
gen4_turboat $0.05 per second. - Gen-4 Image: a separate image-generation model, not Gen-4 video pricing. (Runway’s Gen-4 Image guide)
- Gen-4.5: a different video model. Do not use its prices or credit rates as a substitute for Gen-4’s. (Runway’s Gen-4.5 guide)
Bottom line: For standard Gen-4 in the app, budget 12 credits per second and choose a plan based on your expected monthly credit use. For a documented API estimate, Gen-4 Turbo costs $0.05 per second; the official API references cited here do not establish a standard Gen-4 API route or rate.
