Sulphur2

What is Sulphur2?

Sulphur 2 is an open-source AI video model made for ComfyUI creators who want cinematic motion, strong temporal coherence, and full local control. It runs on your own hardware, so there are no cloud queues, no API keys, and no subscription fees. The model is a 9B parameter system fine-tuned from LTX architecture, with text-to-video and image-to-video support. It is designed for users who want movie-like results and are comfortable with serious GPU requirements. Sulphur 2 is MIT licensed, works with PyTorch and ComfyUI, and focuses on uncensored generation for creative workflows.
