How to run LTX-2.3-Sulphur2-Base-Diffusers
- 01
Rent a GPU
Pick one of the GPUs above. Billing is per second; stop the machine and you stop paying.
- 02
Open a terminal or Jupyter
Connect over SSH or open Jupyter in your browser. PyTorch and CUDA are ready to use.
- 03
Download and run the model
Run the commands below. The weights download straight from Hugging Face to your machine.
pip install -U diffusers transformers accelerate
huggingface-cli download CalamitousFelicitousness/LTX-2.3-Sulphur2-Base-Diffusers --local-dir ./model
python -c "import torch; from diffusers import DiffusionPipeline; p = DiffusionPipeline.from_pretrained('./model', torch_dtype=torch.bfloat16).to('cuda'); print(p)"Why run it yourself?
Hosted video tools charge per clip or per month and put you in a queue. On your own GPU you pay only for the time it runs, make as many clips as you like and keep your prompts and files on your machine.
Questions
- How much GPU memory does LTX-2.3-Sulphur2-Base-Diffusers need?
- By our estimate about 47 GB for inference (19B parameters). Higher resolution, longer context or bigger batches need more.
- How much does it cost to run LTX-2.3-Sulphur2-Base-Diffusers?
- From $0.62 per hour on CMP 170HX, billed per second. Ten hours cost about $6.20.
- Do I need a subscription?
- No. You pay only for the time your machine runs, from your USD balance. Stop it whenever you are done.
