Maximum speed, minimum cost, and the fastest iteration loop. Here is where LTX 2.3 Pro stands out based on real benchmark scores.
Scored 9.0/10 on generation speed — the highest of any model we tested. Prompts return finished clips faster than any competitor, letting you iterate on creative ideas in real time instead of waiting minutes per generation.
At 5 credits per second with an 8.5/10 efficiency score, LTX 2.3 Pro is almost as cheap as Veo Lite while delivering faster output. Generate massive batches of ad variations without burning through your budget.
The combination of fastest speed and lowest cost means you can treat AI video like a brainstorming tool. Generate, review, adjust, and regenerate — all in the time other models take to produce a single clip. This rapid feedback loop finds winning concepts faster.

If speed and cost are your top priorities and your ads do not rely on realistic people, LTX 2.3 Pro is the fastest path from prompt to published ad. It scored 9.0 on generation speed and 8.5 on cost efficiency — the best operational scores of any model tested. The trade-off is clear: quality averages lower than competitors, and human content is its weakness at 5.5/10. Use it for rapid iteration and discovery, then upgrade to a higher-quality model for the final version.

LTX 2.3 Pro is an AI video generation model from Lightricks, the company behind popular creative tools like Facetune and Videoleap. It generates short video clips from text prompts or images at 480p to 1080p natively, with built-in upscaling support to 4K — a capability no other model currently offers.
At 5 credits per second with a 9.0/10 generation speed score, it is the fastest model in our benchmarks. Clips come back almost immediately, which fundamentally changes how fast you can iterate on creative ideas. For context, in the time it takes a slower model to generate one clip, LTX can produce several.
The trade-off is quality. LTX 2.3 Pro's average quality score (6.5/10) is the lowest in our lineup, and its human realism score (5.5/10) makes it a poor fit for people-focused content. But if your ads are built around products, environments, motion backgrounds, or abstract visuals — and you value speed and cost above all else — LTX fills a specific and valuable role.
LTX 2.3 Pro is built for speed and scale. Based on our benchmarks, here is where that speed matters — and where you should use a different model.
Rapid creative testing: This is LTX's core use case. When you need to test 30-50 hooks, product angles, or background concepts in a single session, the 9.0 generation speed means you can iterate in near-real-time. Submit a prompt, review the output, adjust, and regenerate — all faster than any other model allows.
Motion backgrounds and B-roll: Abstract color gradients, flowing textures, particle effects, and atmospheric scenes do not require high human realism or photorealistic detail. LTX handles these well and fast, making it practical for generating video backgrounds that sit behind text overlays or product imagery in your final ad.
4K placements: YouTube pre-roll on desktop, Connected TV campaigns, and digital signage all benefit from higher resolution. LTX 2.3 Pro generates at up to 1080p natively and supports upscaling to 4K — no other model goes beyond 1080p. If your campaign includes large-screen placements alongside social ads, LTX covers the high-resolution requirement.
Product shots at scale: Product rotations, flat-lays, and simple object reveals score 7.0/10 — decent enough for testing variations. Generate a large batch with LTX, identify the best-performing concepts, then optionally re-generate the winners with Veo 3.1 Fast for a polished final version.
Where to use other models: Any ad with a person speaking, gesturing, or expressing emotion. LTX's 5.5/10 human realism is the lowest in our lineup — talking heads, influencer content, and UGC-style ads should go to Kling O3 (9.0 human realism). For higher quality product shots without the speed trade-off, use Veo 3.1 Lite.
LTX is your speed tool, not your quality tool. Use it for the discovery phase — testing hooks, angles, backgrounds, and concepts. Plan to switch to a higher-quality model (Veo Fast or Veo Lite) for the final polished creative if needed.
LTX responds well to straightforward prompts. Focus on the scene, lighting, and motion: "Supplement bottle rotating on a white surface, soft gradient background, clean studio lighting, product commercial style, 9:16 vertical." Keep it simple — the model's speed advantage shines when you can iterate quickly, not when crafting one perfect prompt.
This is where LTX earns its value. Generate 10-20 variations of each concept in rapid succession. The fast turnaround lets you treat AI video like a brainstorming tool — generate, review, adjust, repeat. At 5 credits/sec, a batch of ten 6-second clips costs about 300 credits.
If your campaign includes YouTube pre-roll on desktop, Connected TV, or digital signage, use LTX's 4K upscaling to deliver higher resolution output. For social-only campaigns (TikTok, Reels, Stories), 1080p is sufficient and generates faster.
Add text overlays, CTAs, logos, and voiceover in post-production. The raw video is your starting material — the final ad comes together in CapCut, your ad platform's editor, or any lightweight video tool. Upload to your ad manager and run multiple creative variations per ad set.
LTX 2.3 Pro is an AI video generation model from Lightricks, the company behind Facetune and Videoleap. It is the fastest model in our benchmarks (9.0/10 generation speed) and the only model that supports upscaling to 4K resolution. It generates natively at 480p to 1080p with built-in 4K upscaling. Built for advertisers who prioritize speed, cost, and high-resolution output.
Nearly. At 5 credits per second, LTX 2.3 Pro is very close to Veo 3.1 Lite (4 credits/sec). The difference is negligible in practice, and LTX compensates with faster generation speed, meaning you get your clips back sooner. For pure cost per second, Veo Lite edges it out; for cost per hour of productive work, LTX may be more efficient.
Two things: it is the fastest model we tested (9.0/10 speed), and it is the only model that supports upscaling to 4K resolution. It generates natively at 480p to 1080p, then upscales to 4K — no other model goes beyond 1080p. If you need higher resolution for YouTube pre-roll, Connected TV, or large-screen placements, LTX is currently the only option.
Both are budget-friendly volume models. Veo Lite has slightly better quality scores across the board (6.9 avg vs 6.5 avg) and costs 1 credit less per second. LTX Pro is faster and offers 4K output. Use Veo Lite when quality matters more; use LTX Pro when you need the fastest turnaround or 4K resolution.
This is LTX 2.3 Pro's weakest area. It scores 5.5/10 on human realism — the lowest of all models we tested. Talking heads, facial expressions, and body movement look noticeably less convincing than other models. For any ad that features a person prominently, use Kling O3 (9.0 human realism) instead.
Yes. LTX 2.3 Pro generates video in 9:16 vertical format. For TikTok and Reels, 1080p output is sufficient and matches platform specs. The 4K option is more relevant for YouTube pre-roll and Connected TV placements where higher resolution matters.
Yes. Videos generated with LTX 2.3 Pro can be used commercially in paid advertising across all major platforms. There are no additional licensing fees beyond the generation credits.
LTX 2.3 Pro generates clips of 4, 6, or 8 seconds. The fast generation speed means you can produce and review multiple clips in the time it takes other models to generate one. For longer ads, stitch multiple clips together in an editor.
