LTX 2.3
LTX 2.3 is Lightricks’ video model. We test the Pro text-to-video and image-to-video endpoints on fal, at 1080p with native audio. The current Pro schema accepts 6, 8 or 10 seconds, despite broader family marketing describing longer clips.

Anvisha's take
LTX 2.3 Pro returned all nine requests at 1080p, using six seconds because the endpoint does not accept five. Its style test has angular, print-like waves and the pour keeps the kettle and filter in view. The title-card text is visibly garbled, and the spill frames show the glass suspended above the table, making physics a weak point on this run. The estimated set cost is $4.32 using the current $0.08-per-second widget, not the lower number still in fal’s descriptive copy. Audio was not scored by ear.
LTX 2.3 real output: the same 9 clips every model gets
Every video model on this site gets the same 9 clips, so you can compare like with like. These are the clips LTX 2.3 returned, one try each, nothing re-rolled or retouched. Each tile shows one frame of the clip until you press play. Generated on . The 9 clips took 54 to 73 seconds each and cost $4.32 in total.
A clean product shot that holds its shape through a full slow rotation.
