Quick take
A cost-conscious Kling model on fal for fluid five- or ten-second clips generated from text or a starting image.
Kling 3.0 is newer and offers features that 2.5 lacks, including native-audio options. Compare real project outputs before choosing the older endpoint only on price.
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.

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 request header prevents payload storage, but uploaded CDN files can remain accessible and need separate lifecycle handling.
