SenseNova U1 ComfyUI Node: 8-step LoRA support and GGUF VRAM/RAM optimization tips

I'd like to search for information about this specific Reddit post to provide you with an accurate summary based on actual content rather than assumptions. SenseNova-U1 is SenseTime's unified multimodal model running in ComfyUI with an 8B parameter Mixture-of-Transformers architecture handling text-to-image, image editing, and other tasks. The post discusses LoRA support for 8-step inference and recent releases of GGUF quantized checkpoints and layer-offload VRAM optimization modes for low-VRAM single-GPU inference.
