Model comparison
Compare MiniMax H3 Max and LTX-2.5 Fast using the same provider-sourced video generation rubric. No mystery score and no invented benchmark ranking.
Facts checked September 14, 2026
Set your usage. Your estimate updates as you type.
Example: 8-second, 720p clips with audio. Models that do not support these settings will not receive an estimate.
Estimates exclude taxes, tools, cache storage/writes, free allowances and custom discounts. Image estimates cover output only, not prompt or reference-image charges. Quality modes differ by model. Unlisted settings are not treated as free.

Quick take
fal's speed-focused post-trained version of MiniMax H3 for short video with native audio, fast 768p iteration, and text, image, or multimodal reference input.
fal's roughly 2.46-second figure is backend inference for one five-second 768p test—not total wait time or an SLA. H3 Max is hosted by fal, its weights are not published, 1080p is refined from the native 768p path, and reference media can add meaningful token cost.
LTX's speed-optimized video model for text, image, or audio input, native sound, automatic duration, and output up to 4K.
Fast does not mean every 4K job finishes instantly. Price grows from $0.09 to $0.30 per generated second, and permitted duration depends on resolution and frame rate.
Compare the published facts
Values use each provider's own published units and limits. A blank means the provider did not publish a directly comparable value in the sources reviewed.
| Video generation | MiniMax H3 Max | LTX-2.5 Fast |
|---|---|---|
| Generation priceCurrent list price per generated second or the provider's closest billing unit. | $0.05 480p · $0.08 768p · $0.16 1080p / sec | $0.09/s 720p to $0.30/s 4K |
| Clip durationDocumented duration choices or maximum clip length. | 5–15 seconds | 6–20 seconds depending on resolution and frame rate |
| Maximum outputHighest provider-documented output resolution, with relevant constraints. | 1080p latent refinement; 768p native | 4K |
| Native audioWhether the endpoint generates synchronized audio with video. | Yes | Yes; can also generate silent video |
| Input modesSupported text, image, video, reference, or motion inputs. | Text, first/end image, or image/video/audio references | Text, image, or audio; optional last frame and camera motion |
| Generation timeOnly shown when a provider publishes a range; not a Cody benchmark. | fal test: ~2.46s inference for a 5s 768p clip | Fast tier; exact time not published |
How to choose
Start with the job you need to complete, then validate cost, access, and policy details on your exact provider route.
fal stores request inputs and outputs by default. The X-Fal-Store-IO: 0 header prevents payload storage, but separately uploaded CDN inputs can remain accessible and need their own deletion or lifecycle handling.
The reviewed public LTX model and pricing guides do not state one complete endpoint-specific retention or training-use commitment. Verify current account and enterprise terms for sensitive media.
