How to run LTX-2 and LTX-2.3 without a GPU
How can I run LTX-2 and LTX-2.3 without a GPU or a local install?
LTX-2 and LTX-2.3 have open weights, so you can run them yourself, but you need the hardware: Lightricks asks for an NVIDIA GPU with at least 32GB of VRAM. Without a GPU, the simplest route is a hosted version. In OTOY Studio, LTX-2 and LTX-2.3 run in the browser from 33 credits (€0.33) per run, with nothing to install, on the same canvas as 100+ other image, video and 3D models.
Lightricks' fast video models: text and image to video with synchronized audio, plus an audio-to-video mode that animates an image to a soundtrack.
Running it yourself
| Open weights | LTX-2 and LTX-2.3 are on Hugging Face, including fp8 variants. |
| License | LTX-2 Community License. Commercial use is free for companies with under $10 million in annual revenue. Above that, Lightricks requires a paid commercial license. |
| Hardware | Lightricks' system requirements call for an NVIDIA GPU with at least 32GB of VRAM ("more is better"), 32GB of RAM and 100GB of disk. The recommended setup is an A100 80GB or H100 with 64GB+ of RAM. fp8 quantization and CPU or disk offload lower the memory needed. |
| Operating system | NVIDIA GPU with a recent CUDA. Some components are Linux-only, with fallbacks on Windows and macOS. |
| ComfyUI | Yes. LTX-2 and LTX-2.3 are natively supported in ComfyUI. |

Run it yourself if: You have a 32GB+ GPU and want IC-LoRA controls, your own fine-tunes, or unlimited drafts at no per-run cost.
