LTX models
5 LTX models on Hugging Face, from 1.9B to 19.0B parameters. At the precision each one is published in, the smallest needs about 4.3 GB of VRAM (LTX-Video-0.9.5, cheapest live fit: RTX 5060 Ti) and the largest about 42.4 GB (LTX-2.3-Diffusers, cheapest live fit: RTX A6000). The cheapest way to run LTX-Video-0.9.5 is $0.110/hr.

VRAM is for the precision the model is published in, with the same overhead and an 8,192-token context assumed on every page; see the methodology. The fit shown is the lowest-priced single GPU type that holds the model at that precision, or the lowest-priced multi-GPU set (up to 8) when none does.
