How it works
Estimate Windflow's ready-session meter using the published model rate. Cost equals rate per ready second × ready seconds per session × independent sessions. Shared viewers do not add an independent generation meter. Queueing and startup are excluded; ready time can continue while delivery is paused.
- Choose the model you intend to run.
- Enter ready minutes per session and independent sessions per day.
- Compare daily and monthly generation cost. Adjust duration or concurrency before launching.
Common questions
- How do I calculate an AI video API session cost?
- Multiply the model's published ready-second rate by its ready duration and the number of independent sessions. This calculator uses Windflow's public model catalog.
- Do concurrent sessions change the rate?
- Each independent session carries its own meter. Concurrency changes total cost and required capacity, rather than the listed per-second rate.
- Does this include hosting my own GPU?
- The estimate covers Windflow's published session meter. Self-hosted GPU rental, staff and infrastructure need a separate estimate.
