Can I run LTX-Video 2B on Nvidia GeForce RTX 3060 Ti (8GB)?
Needs ~10 GB at fp8 + offload, but only ~7 GB is usable on Nvidia GeForce RTX 3060 Ti (8GB). With aggressive CPU offload it can run on as little as ~6 GB, much slower.
Needs ~10 GB at fp8 + offload, but only ~7 GB is usable on Nvidia GeForce RTX 3060 Ti (8GB). With aggressive CPU offload it can run on as little as ~6 GB, much slower.
The gap is about 3 GB: LTX-Video 2B needs roughly 10 GB and Nvidia GeForce RTX 3060 Ti (8GB) leaves only about 7 GB usable for a model. The lightest tracked hardware that runs LTX-Video 2B is the Nvidia GeForce RTX 3060 (12GB) at 12 GB. See LTX-Video 2B on Nvidia GeForce RTX 3060 (12GB).

FAQ
Can Nvidia GeForce RTX 3060 Ti (8GB) run LTX-Video 2B?
Needs ~10 GB at fp8 + offload, but only ~7 GB is usable on Nvidia GeForce RTX 3060 Ti (8GB). With aggressive CPU offload it can run on as little as ~6 GB, much slower.
How much VRAM does LTX-Video 2B need?
Nvidia GeForce RTX 3060 Ti (8GB) does not have enough memory. At fp8 + offload the realistic peak is ~10 GB of VRAM, versus ~12 GB with every component kept resident (no offload). With aggressive CPU offload it drops to ~6 GB, much slower.
What do I use to run LTX-Video 2B locally?
LTX-Video 2B runs in ComfyUI or Diffusers. It loads as a video diffusion checkpoint plus its text encoder and VAE, not a single chat command.
