Runway Gen-4.5 price: direct answer
Runway Gen-4.5 costs about $1.20 for a 10-second output at the tracked 720p configuration, before retries, taxes or provider-specific minimums. At 100 ten-second attempts, the generation total is $120.
Effective cost after retries
Headline price is not usable-output price. One retry makes a usable ten-second clip approximately $2.40; two retries make it $3.60. Measure acceptance rate by workload because dialogue, product motion and character continuity fail differently.
When Runway Gen-4.5 is a good fit
Its strongest fit is high-quality production work and mature tooling. Require a small representative prompt suite before selecting it for volume. Include both easy and failure-prone scenes, then record cost per accepted output.
Cost examples
| Workload | Generated time | Clean pass | With 2 retries |
|---|---|---|---|
| 10 × 10s clips | 100s | $12.00 | $36.00 |
| 100 × 10s clips | 1000s | $120.00 | $360.00 |
| 1000 × 10s clips | 10000s | $1200.00 | $3600.00 |
Configuration caveats
The tracked rate applies to 720p output and does not include native audio. Input-video billing, minimum charges, upscaling, storage and editing may change the final production cost.
