ModAPISPRICE COMPARISON · cheapest ai video generation api
Cheapest AI Video Generation API (2026 Compared)
The cheapest video generation API depends on the unit you're buying: a low per-second rate with minute rounding can cost more per clip than a flat per-clip price. This category table normalizes list prices across the major providers. ModAPIS rows are generated from our live catalog; third-party rows arrive with the first price capture.

Billing traps in this category
- Per-second vs per-clip billing — a low per-second rate with rounding can cost more per output (each row's Unit column spells this out).
- Whether failed generations are charged — some providers bill attempts, not successes; ModAPIS charges only successful runs.
- Credit expiry and bundle conditions — promotional credits often expire or exclude specific tiers.
- TODO(price-snapshot): provider-specific traps with sources, filled with the first price capture.

Disclaimer
All prices are the list prices published on each provider's own pricing page, captured on pending first capture (TODO price-snapshot). They exclude promotions, credit bundles, and negotiated volume rates, and may have changed since capture — always verify on the provider's site before you buy.

Quick answers
Where do these prices come from?
From each provider's own public pricing page, captured on the snapshot date shown above the table. We record list prices only — no promotions, credit bundles, or negotiated volume rates — and every row links to its source. How often is this table updated?
Monthly, on the first working day. When a price moves by more than 5%, we update the row and refresh the page's last-modified date the same day. Why does a price here differ from what I see at a provider?
Promotions, credit bundles, and volume tiers are excluded by design, and list prices change between captures. Always verify on the provider's pricing page (linked in each row) before you buy.
