Overview
What is Sulphur 2?
Sulphur 2 is an uncensored, open-weights AI video generator fine-tuned on Lightricks LTX 2.3. It is a community-released model designed to run locally on consumer GPUs. The release includes base weights, distilled LoRAs for faster generation, and specialized ComfyUI workflows. It focuses on high-fidelity realism by training on approximately 125,000 video clips while intentionally excluding 2D animation. As a derivative of the LTX 2.3 DiT-based foundation model, it supports both text-to-video and image-to-video tasks and includes a local prompt enhancer based on Qwen 3.5 to maintain a fully on-device creative pipeline.
