LTX 2.3 Fast
Quick drafts from the 4K model. Half the cost.
LTX 2.3 Fast is the efficiency variant of Lightricks' 22-billion parameter model. Same architecture, faster inference, 50% lower cost. Ideal for rapid iteration and batch content creation before promoting the best candidates to Pro for final rendering.
Example outputs
“A dog sprinting across a park and leaping to catch a frisbee, landing and trotting back proudly, sunny day, playful energy”
“A matte black concept car drifting through an empty underground car park, tyres smoking, neon strip lights reflecting off the wet concrete floor, cinematic low angle”
“A fantasy warrior charging across a burning bridge toward a collapsing fortress, debris flying, dramatic wide shot, epic game cinematic trailer”
“A time-lapse of a sunset over city rooftops, clouds streaking across the sky, street lights flickering on one by one below”
“A butterfly gliding in and landing on a flower, wings slowly folding closed, macro close-up, soft garden light”
“A basketball spinning on a fingertip then tossed upward, camera following it in dramatic slow motion, dark gym, single spotlight”

LTX 2.3 Fast shares the same 22-billion parameter architecture as Pro but optimises for speed and cost. Generate drafts and concepts at half the cost, then upgrade the best candidates to Pro for the final render.
Audio is still generated in a single pass. Portrait mode, multi-subject prompts, and the rebuilt VAE are all present. The trade-off is slightly less fine detail at the pixel level.
Draft-then-promote workflow
Generate 10 variations with Fast, pick the best, then render the final version with Pro. Lower total cost than generating 3 Pro clips to find the right one.
