Yes — LTX 2.3 is free to use. Lightricks released the model under a permissive open-source license, so you can download the weights, run it locally, and generate as much video as your hardware allows without paying anyone. The catch is that running the 22B-parameter model takes serious GPU horsepower (roughly 32 GB VRAM for FP8), and downloading the full weights, encoders, and LoRAs is around 60 GB of data. This guide walks through every way to use LTX 2.3 — free or paid — and what each one actually costs.
Quickest free path with no install: our AI Porn Generator runs LTX 2.3 in your browser with 160 free tokens per day for any signed-up user. That's enough for several test clips daily. For unlimited local use, our ComfyUI Workflow Pack is a one-time purchase with the full LTX 2.3 stack and Discord access for ongoing updates.
The Five Ways to Run LTX 2.3
| Option | Cost | Setup Time | NSFW | Best For |
|---|---|---|---|---|
| Self-host (your GPU) | Free + electricity | 2–4 hours | Yes | Heavy users with 24+ GB VRAM |
| Cloud GPU (RunPod / Vast) | $0.30–0.80/hr | 30 min | Yes | Bursty workloads |
| Replicate / Fal API | $0.05–0.20/clip | 5 min | Limited | Programmatic SFW use |
| VirtuaVixen Studio | Free 160 tokens/day, then token packs from $4.99 | 0 min | Yes | Most users |
| Workflow Pack + your GPU | One-time pack purchase | 15 min (installer) | Yes | Power users, custom LoRAs |
Free Self-Host on Your Own GPU
If you have an NVIDIA card with at least 24 GB VRAM (RTX 3090, 4090, 5090, A6000, A100), you can run LTX 2.3 entirely free using ComfyUI. Total cost: $0, plus whatever your electricity bill comes to (a 4090 generation runs ~30W idle and ~450W peak).
You'll need to download:
- LTX 2.3 22B Distilled or Dev model (~22 GB at FP8)
- LTX 2.3 audio VAE + video VAE (~3 GB)
- Gemma 3 12B text encoder (~10 GB) — or the abliterated variant for NSFW
- Custom node packs for ComfyUI (LTX nodes, KJNodes, pysssss extras)
- Any LoRAs you want

Is There a Free LTX 2.3 API?
There is no official free LTX 2.3 API from Lightricks. Their hosted offering on Lightricks's own platform charges per generation. However, several third-party platforms offer LTX 2.3 with free tiers or trial credits:
- Replicate — pay-per-generation, ~$0.05–0.10 per 5-second clip. Free new-user credits sometimes available.
- Fal.ai — similar pricing to Replicate. Generally NSFW-restricted.
- RunPod — rent GPU time by the hour ($0.30–0.80/hr depending on card). Self-deploy ComfyUI or use community templates.
- Google Colab Pro — limited GPU access for ~$10/mo. Free Colab is too constrained for LTX 2.3.
- VirtuaVixen Studio — 160 free tokens/day, no credit card. NSFW-friendly.
For programmatic use cases, the closest thing to “free” is RunPod — you only pay for active GPU time. Spin up a 4090 instance, generate a batch, shut it down. Cost for 100 clips might be $5–10 if you're efficient. Full breakdown in Running LTX 2.3 in the Cloud.
VirtuaVixen Studio: Free Daily Tokens
For most users, the easiest way to use LTX 2.3 is our hosted Studio. Sign up free, get 160 tokens per day automatically, and you can run any of our LTX 2.3 workflows directly:
- LTX 2.3 BJ Cinema (60 tokens)
- LTX 2.3 Doggy Cinema (60 tokens)
- LTX 2.3 Sex Cut Cinema (60 tokens)
- LTX 2.3 FML Frame Basic (60 tokens)
- LTX 2.3 Lip Sync (60 tokens)
That's 2–3 free clips daily, no install, no GPU. If you want more, token packs start at $4.99 for 300 tokens (5+ clips). All NSFW workflows allowed.
When You Should Pay (and When You Shouldn't)
Don't pay if: you generate occasional clips, you have a capable GPU, you don't mind a 2–4 hour first-time setup. Self-host and you'll pay nothing forever.
Pay for cloud GPU rental if: you generate in bursts (a few hundred clips a month, then nothing), or you don't have a 24+ GB GPU. RunPod is the cheapest way to get GPU time when you need it.
Pay for our Studio if: you don't want to manage a ComfyUI install, you don't have a powerful GPU, and you want every workflow ready to go with no setup. The free tier covers light use; token packs cover heavy use without per-second pricing.
Pay for our Workflow Pack if: you want full local control with the convenience of an installer. The pack pulls the abliterated text encoder, all model weights, the NSFW LoRAs, and the workflow JSONs from our Hugging Face repo with one command. New workflows are pushed weekly to Discord.
Try Both Free Options
The simplest decision tree: if you have a powerful GPU and a free weekend, self-host using our installation guide. If you don't, sign up for our Studio and burn through your free daily tokens before you commit to anything paid. Both options give you full uncensored LTX 2.3 access — see what fits your workflow before deciding.
