What you need to run it
- Mac
- Yes, but slow. Any Apple Silicon Mac (M1 or newer) with at least 32 GB (96 GB recommended) of memory. It runs, but much slower than on an NVIDIA card.
- Windows / Linux PC
- NVIDIA works best. A graphics card with at least 32 GB (80 GB recommended) of video memory.
- No graphics card
- Not practical. Too slow without a graphics card or Apple Silicon.
On a Mac it only runs through an experimental community MLX port, and it needs a lot of memory (about 15 GB at the very least, 50 GB or more at full quality).
Numbers are for: Full-quality build for recommended; the compressed distilled build for the minimum. Based on the maker’s own figures; where the maker gives only a graphics-card figure, the Mac memory is our estimate.
Strengths
- Video and matching audio in one pass, plus audio-to-video for music videos
- Native multi-shot scenes, automatic clip length and native 4K HDR / EXR output for post-production
- Free for commercial use under $10M annual revenue, including self-hosting and fine-tuning
- Base checkpoint for fine-tuning, a LoRA trainer and day-one ComfyUI support
Weaknesses
- Free for commercial use only under $10M annual company revenue (LTX-2.x Community License) — above that you need a paid licence
- Needs a data-centre GPU: Lightricks targets 80 GB or more of VRAM, or 32 GB for the distilled model with quantisation
- Roughly 66 GiB of weights to download; gated on Hugging Face, licence accepted on download

Change log
- — Added hardware requirements (Mac support, memory, NVIDIA). Source: Lightricks' 80 GB target (32 GB for the distilled quantised build) and the community MLX port's measured memory; Mac minimum is conservative.
- — Initial entry. Released 2026-08-11 (LTX newsroom, 'Introducing LTX-2.5'), under the LTX-2.x Community License Agreement — free commercial use under $10M annual revenue. Added 2026-10-28 from the popularity sweep: 2.16M Hugging Face downloads in the last month, 9.6k likes, 9.9k GitHub stars, and the top trending image-to-video model on Hugging Face.
