What does the LTX API cost?

Updated July 08, 2026 10:46

LTX API pricing is charged per second of generated video. The rate depends on the model tier, resolution, and generation type you use.

Where to find current prices

Pricing is maintained on the LTX API pricing page. It covers per-second rates for each model tier (ltx-2-3-fast and ltx-2-3-pro), resolution, and generation type.

What affects the cost

Model tier — ltx-2-3-pro costs more per second than ltx-2-3-fast.
Resolution — higher resolutions (up to 4K) cost more per second.
Generation type — text-to-video, image-to-video, and audio-to-video each have their own rates.
Output duration — you're charged per second of video generated, so a longer clip costs more.

If pricing is updated, the rate at which your existing credits are consumed will change. Your credit balance stays the same, but the amount of video you can generate may go up or down. See the API Credit Terms for details.
