LTX 2.3 NSFW: Uncensored Fast Video Generation, Now on Siray

Open-weight video models keep getting faster and sharper, and the NSFW community keeps finding them first. Lightricks' LTX 2.3 is the latest example: a 22-billion-parameter model that ships in a checkpoint fast enough for real production turnaround and hands out its weights under an open license. That combination is exactly why LTX has become a name uncensored creators watch closely — and it's now live and ready to use on Siray.

Key TakeawaysLTX 2.3 is Lightricks' 22B-parameter open-source video model, generating native 4K video at up to 50 FPS with synchronized audio in one pass.It ships in four checkpoints — dev, distilled, fast, pro — with the distilled variant completing generation in as few as 8 denoising steps.Open weights (LTX-2 Community License) mean the community can fine-tune filter-free variants, the same structural reason other open video models became uncensored hubs.LTX 2.3 is available now on Siray, hosted through one API key, with no local GPU required.

What LTX 2.3 Is

Lightricks released LTX 2.3 on 2026-03-05 as a 22-billion-parameter open-source video model, built on the same diffusion transformer (DiT) architecture as October 2025's LTX-2. Rather than a ground-up rebuild, 2.3 is a targeted refinement: a rebuilt VAE for sharper fine detail and a text connector roughly 4x larger for parsing complex prompts. On Siray, LTX 2.3 runs at 24/30 FPS from a checkpoint tuned for fast production turnaround. On the Artificial Analysis Text-to-Video Arena, LTX 2.3's Fast checkpoint holds an Elo score of 1,121 — the top spot among open-weight video models, ahead of Wan 2.2 and Wan 2.1 — though proprietary systems like Seedance 2.0 (Elo 1,273) still lead on raw benchmark quality.

Built for Speed and Clip-by-Clip Work

LTX 2.3 ships in four checkpoint variants — dev, distilled, fast, and pro — so creators can trade quality for turnaround depending on the job. The distilled checkpoint can complete a generation in as few as 8 denoising steps. Beyond straight text-to-video, LTX 2.3 supports image-to-video, so a creator can drive a clip from a reference frame. Native portrait output at 1080×1920 covers vertical-first platforms directly, and on Siray generation runs at 24 or 30 FPS depending on the checkpoint.

Open Weights, No Built-In Filter

Lightricks distributes LTX 2.3's weights on Hugging Face under the Apache-2.0 license — free for commercial use and self-hosting, with no revenue cap. That's the same structural fact behind every other open-weight video model already covered on this blog: once weights are public, whoever runs them decides what filtering, if any, applies. There's no closed-API gateway checking every request, so LoRA-style uncensored fine-tunes tend to appear quickly around any capable open release. It's also why searches for ltx unrestricted ai video are already picking up — LTX 2.3's speed and quality make it a particularly attractive base for that kind of community tuning.

Available on Siray

The full 22B-parameter LTX 2.3 model is live on Siray now — no Hugging Face download, no local GPU queue, no juggling checkpoints by hand. One API key covers text-to-video and image-to-video, normalized the same way as every other model in Siray's catalog. Creators who prefer working through ComfyUI can reach LTX 2.3 the same way: install the siray-comfyui node — search "siray-comfyui" in ComfyUI Manager, or grab it from github.com/siray-ai/siray-comfyui — to bridge a local workflow into Siray's 300+ hosted models. No downloading LTX 2.3's weights, no VRAM upgrade, and new accounts get free credits to start.

FAQ

What is LTX 2.3?

Is LTX 2.3 uncensored?

• Lightricks doesn't market it that way. Its open, permissively-licensed weights mean the community can fine-tune filter-free variants, which is why NSFW/uncensored activity clusters around LTX releases.

Is LTX 2.3 available on Siray?

• Yes — the full 22B-parameter model is live now, not a future release. Text-to-video and image-to-video both run through the same one-API-key setup as the rest of Siray's catalog.

How fast is LTX 2.3?

• The distilled checkpoint can complete a generation in as few as 8 denoising steps, among the fastest turnarounds of any open video model currently available.
