    Great model and incredible to not see this locked behind a paywall. Tons of respect!

    You can get quantized models that make the model smaller so it can run on your hardware like GGUF.

    How can people run this? 50GB VRAM?

    gpu rentals if you want the full thing. otherwise distilled and quantified version of it are now out. still need a decently large amount of vram tho.

    Professional GPUs. Blackwell RTX 5000 with 48 or 72 GB of VRAM. Blackwell RTX 6000 with 96 GB of VRAM. These GPUs can be bought from places like Central Computers, but the cost is $5000-$9000. The minimum LTX recommends to have it run at all is 32 GB of VRAM, which is what the 5090 has.

    I have the distilled model, and it gets the job done, while it gets the PC hanging, 32GB RAM and RTX3080 10GB, (using Pinokio)

    Same here. Have you managed to get the upscalers work? Mine crashes whenever during gen when I activate them.

    how long does it take you to render out segments?
