Prompt checklist
What a video prompt carries, part by part. The check marks are simple tests of what you typed, not a promise of how the video turns out.
Subject and action first — In your prompt
The setting in one clause — Tip
Where and when: a street market on a wet evening. One place and one stretch of time; a new place is a new clip.
The light and where it comes from — Tip
One shot size and one camera move — Tip
The look, once — Tip
Behavior, not mood — Tip
What is heard — Tip
The length and the frame — Set by the settings
Set by the aspect ratio and length pills.
The length is the whole video’s: DreamBench plans the scenes, makes each one with LTX-2.3 and joins them. Create with LTX-2.3 opens Film Studio with your prompt and every setting in place.
Strengths
What LTX-2.3 is good at
- 01
Made for vertical too
Lightricks trained LTX-2.3 on portrait footage, so 9:16 video is composed for a phone screen instead of being cropped from a 16:9 frame.
- 02
Movement from a still
Lightricks retrained its image-to-video so a single frame more often turns into genuine movement, with fewer frozen clips and fewer slow pan-and-zoom shots. Name a specific action and a camera move in your prompt, and give the scene new direction if a clip still sits still.
- 03
Crisper textures and edges
Lightricks rebuilt the model’s image encoding, so fine textures, hair, lettering and edges keep more of their detail.
- 04
Sound in the same pass
With sound on, LTX-2.3 generates stereo audio together with the picture, and Lightricks filtered its training data for fewer artifacts and dropouts.

The model
What is LTX-2.3?
- Made by Lightricks
- Released March 2026
- Video model
- Clips up to 10 seconds
LTX-2.3 is a video model from Lightricks, released in March 2026. It generates picture and stereo sound together in a single pass, and Lightricks publishes its weights openly as well.
Compared with LTX-2, Lightricks reworked it for sharper textures, hair and edges, closer attention to complex prompts, cleaner sound and livelier movement when it animates a still image. It was also trained on vertical footage, so 9:16 video isn’t cropped from a widescreen frame.
Lightricks now calls LTX-2.3 its previous generation: LTX-2.5, released in August 2026, is its current model, and LTX-2.3 remains fully supported.

Heron at dawn
Hand-painted watercolor animation, vertical 9:16. A gray heron stands still in a misty reed bed at dawn, then unfolds its wings and lifts off low over the water. Loose washes of pink and gold bleed at the edges, and the paper’s texture shows through every ripple. Reeds rustling, water dripping from its feet, one soft call.
Low-poly lighthouse
Widescreen 16:9, low-poly 3D animation. A faceted lighthouse on a cliff sweeps its beam across a flat-shaded sea at dusk, while geometric waves roll in and break into triangles of foam. Polygon clouds drift past a pale, many-sided moon, and a tiny boat bobs home toward the harbor. Soft surf and a slow, humming wind.
Gold into blue
Widescreen 16:9 abstract macro, 10 seconds. Drops of molten gold fall in slow motion into a pool of deep blue oil and bloom into marbled swirls, catching the light as they spread and fold into each other. Tiny bubbles rise through the color. No people, no objects, no text, just a low, warm hum.

LTX-2.3 FAQ
What is LTX-2.3?
LTX-2.3 is a video model from Lightricks, launched in March 2026. It generates picture and sound together in one pass, in widescreen or vertical video, and Lightricks also publishes its weights openly.
Is LTX-2.3 Lightricks’ latest model?
No. Lightricks released LTX-2.5 in August 2026 and now calls LTX-2.3 its previous generation, while keeping it fully supported. DreamBench offers LTX-2.3.
How is LTX-2.3 different from LTX-2?
Lightricks rebuilt the image encoding for sharper textures, hair and edges, made the model follow complex prompts more closely, cleaned up the sound and improved image-to-video. It also trained it on vertical footage, so 9:16 isn’t cropped from a widescreen frame.
What’s the difference between LTX-2.3 and LTX-2.5?
LTX-2.5 is Lightricks’ newer model, released in August 2026. It adds connected shots in one generation, a clip length the model picks from the action, and HDR output. Lightricks keeps LTX-2.3 fully supported as its previous generation, and DreamBench offers LTX-2.3 at 720p, 1080p and 4K.
How long can an LTX-2.3 video be on DreamBench?
Each clip LTX-2.3 generates on DreamBench runs up to 10 seconds. A whole video can be longer, up to 5 minutes depending on your plan, because DreamBench plans the scenes and joins the clips into one video.
What resolution does LTX-2.3 use on DreamBench?
LTX-2.3 videos come in 720p, 1080p or 4K on DreamBench, with 4K on Plus and above. DreamBench uses LTX-2.3 Fast for 720p and LTX-2.3 Pro for 1080p and 4K: Lightricks built Fast for quick iteration and previews and Pro for final renders, so you pick between them by choosing a resolution. Every video is widescreen (16:9) or vertical (9:16), and Lightricks trained the model on portrait footage, so 9:16 is composed for a phone screen rather than cropped.
Does LTX-2.3 make sound?
Yes. With sound on, LTX-2.3 generates stereo audio together with the picture in a single pass, and Lightricks filtered its training data for fewer artifacts and dropouts. On DreamBench a second costs the same with sound on or off; switch sound off in the composer if you want picture only.
How much does LTX-2.3 cost on DreamBench?
LTX-2.3 uses credits for each second of video, at a rate that depends on the resolution and stays the same with sound on or off, plus a base amount per video. The table on this page shows the current rates, and you always see the exact cost before you generate.
Does LTX-2.3 cost anything to use?
Yes. On DreamBench, each LTX-2.3 video uses credits, which come with a paid plan, and LTX-2.3 is on every plan, with 4K on Plus and above. A second costs the same with sound on or off, and the composer shows the exact cost before you generate.
Can I run LTX-2.3 myself?
Yes. Lightricks publishes LTX-2.3’s weights on Hugging Face under its LTX Model License, and companies with more than $10 million in annual revenue need a commercial license from Lightricks. The full model wants a GPU with plenty of memory, and Lightricks offers a quantized version for machines with less. On DreamBench there is nothing to install: pick LTX-2.3 in the composer, in the browser on a phone, tablet or computer, and generate at up to 4K.
What should an LTX-2.3 prompt say?
Say the format, 16:9 or 9:16, and the length, describe the movement you want from the still, then the sound. Lightricks notes that LTX-2.3 turns a still into real movement more often than LTX-2, so name the action rather than the mood.
Should I use LTX-2.3 or Wan 2.7 on DreamBench?
Both are on DreamBench, so run the same brief on each and keep the one you prefer. LTX-2.3 makes clips of up to 10 seconds with stereo sound, in 16:9 or 9:16, at 720p, 1080p or 4K; the Wan 2.7 page, linked below, states its own limits.
Does DreamBench have an LTX-2.3 API?
No. DreamBench offers LTX-2.3 through its composer, in the browser on a phone, tablet or computer, with nothing to install. Developers can use Lightricks’ own API, documented on ltx.io, where the prices and limits are Lightricks’, not DreamBench’s.
Do LTX-2.3 videos have a watermark on DreamBench?
Videos made on the Starter plan carry a small DreamBench watermark; Plus, Ultra and Studio remove it. The sound and picture are otherwise as LTX-2.3 generated them.
