FAQs

How is video generation priced in the LTX API?

Video generation in the LTX API is billed per second — there are no request fees or per-asset charges. Your rate depends on the endpoint, the model variant, and the output resolution.

Text-to-Video and Image-to-Video are billed on the duration of the generated video. Audio-to-Video is billed on the input audio. Retake, Extend, HDR Upscale, and Reframe are billed on the input video.

Current LTX-2.5 rates per second:

ltx-2-5-fast — 720p $0.09 · 1080p $0.13 · 1440p $0.19 · 4K $0.30
ltx-2-5-pro — 720p $0.12 · 1080p $0.17 · 1440p $0.25 · 4K $0.39

Portrait and landscape are priced identically at the same resolution tier.

What factors affect the cost of video generation?

The cost of video generation is determined by:

Billed duration — the generated video on Text-to-Video and Image-to-Video; the input audio or input video on the other endpoints
Output resolution — 720p, 1080p, 1440p, or 4K
Model variant — ltx-2-5-fast, ltx-2-5-pro, ltx-2-3-fast, or ltx-2-3-pro
Endpoint — HDR Upscale and Reframe have their own rate tiers

Higher resolutions and Pro variants have higher per-second costs.

How is pricing calculated for Text-to-Video and Image-to-Video?

Text-to-Video and Image-to-Video use the same per-second rate at every resolution, billed on the duration of the generated video.

With automatic duration, you are charged for the length the model actually produces. On prepaid accounts, credits are held against the longest duration your resolution and frame rate allow, and the unused remainder is released when the job finishes.

How is Retake (video editing) priced?

Retake requires ltx-2-3-pro and is billed at $0.10 per second of the input video you upload, at 1080p.

What is the difference between the Fast and Pro model variants?

Fast is optimized for speed and cost — best for iteration, previews, and high-volume generation.

Pro is optimized for visual fidelity and motion stability, for final and commercial-grade renders. On LTX-2.5, both variants support 720p through 4K.

On LTX-2.3, Pro is also required for Audio-to-Video, Retake, Extend, and Reframe.
