Programmatic Sulphur-2 on RTX 5090 in 2 commands ⚑

There's one config that runs Sulphur-2-base exactly as it was fine-tuned. Quality mode, 720p, 10 s, 24 fps, enhancer on (and running on CPU 64 GB DDR5 with llama.cpp). Anything else is OOD, breaks audio, or both. I built the stack so you don't have to discover that the hard way.

What's it like, being a millionaire?

Does it work on AMD GPUs? Does this work for i2v as well?

@SCUser This model doesn't seem to work very well at all, so I don't know. That's the problem with local AI BTW. Failures are almost always silent.

I2V on this model requires very heavy prompt engineering for good results. T2V is easier, but ultimately, it's all relative to your prompting. The prompt enhancer does a solid job of helping with it.
