LTX-2 API pricing
Usage-based pricing by endpoint and output quality.
Text-to-Video
Designed for quick iteration, previews, and fast creative exploration.
- 1920×1080 — $0.04/sec
- 2560×1440 — $0.08/sec
- 3840×2160 (4K) — $0.16/sec
- Same pricing applies for text input and pure prompt -based generation.
Text-to-Video
Optimized for higher fidelity and increased temporal stability. Best for production-ready output and final renders.
- 1920×1080 — $0.06/sec
- 2560×1440 — $0.12/sec
- 3840×2160 (4K) — $0.24/sec
- Deal for client-facing content or polished deliverables.
- Higher compute level → higher visual quality.
Image-to-Video
Designed for quick iteration, previews, and fast creative exploration.
- 1920×1080 — $0.04/sec
- 2560×1440 — $0.08/sec
- 3840×2160 (4K) — $0.16/sec
- Same compute cost as text-to-video Fast.
- Resolution and duration determine total cost.
Image-to-Video
For detailed, stable motion derived from a still image. Best for high-quality sequences, storytelling, and production use.
- 1920×1080 — $0.06/sec
- 2560×1440 — $0.12/sec
- 3840×2160 (4K) — $0.24/sec
- Uses the Pro rendering path for maximum fidelity.
- Ideal when visual consistency is critical.
Retake - video editing
Refine only the parts that need adjustment - no need to regenerate the whole video. Perfect for fixing scenes, adjusting elements, or improving localized areas.
- 1920×1080 — $0.10/sec
- Currently available in 1080p only.
- Billed per second of input video.
FAQs
How is video generation priced in the LTX API?
Video generation in the LTX API is billed per second of output video. Pricing depends on the selected model and output resolution, not on the number of requests or assets generated.
What factors affect the cost of video generation?
The cost of video generation is determined by:
- Video duration (seconds generated)
- Output resolution
- Model type (ltx-2-fast or ltx-2-pro)
Higher resolutions and premium models have higher per-second costs.
How is pricing calculated for Text-to-Video and Image-to-Video?
Video and Image-to-Video?Text-to-Video and Image-to-Video use the same per-second pricing model. Costs are calculated based on the duration of the generated video, the selected model, and the output resolution.
How is Retake (video editing) priced?
Retake is billed per second of the input video being uploaded, using the ltx-2-pro model at a fixed per-second rate for supported resolutions.
What is the difference between ltx-2-fast and ltx-2-pro?
ltx-2-fast is optimized for speed and cost efficiency, making it suitable for high-volume or iterative generation.ltx-2-pro is optimized for higher visual quality and advanced use cases, with higher per-second pricing.
