GGUF Q4KM conversion of the distilled diffusion transformer from SulphurAI/Sulphur-2-base, packaged with the BF16 text/audio auxiliary components, the full LTX video VAE, and a validated ComfyUI API workflow. This package is designed for older NVIDIA GPUs without native NVFP4 tensor cores. On a modified RTX 2080 Ti 22 GB, it was 2.68× faster and used 3.65 GiB less peak VRAM than the existing Sulphur NVFP4 checkpoint in the same controlled workflow. This is a modified quantized redistribution, not an official SulphurAI or Lightricks release. GGUF tensor layout: 2,672 F32, 28 BF16, 1,376 Q4K, and 368 Q6K tensors. The auxiliary checkpoint contains exactly 4 text-projection, 102 audio-VAE, and 1,227 vocoder tensors, all BF16. The Gemma-3-12B text encoder is not included. Obtain gemma312Bitfp4mixed.safetensors from the upstream LTX/Sulphur text-encoder distribution. Controlled workflow: Q4KM was 2.683× faster, reduced wall time by 62.7%, and saved 3,742 MiB / 3.65 GiB (17.2%) peak VRAM. A separate…

Compatibility and lineage
Language coverage was not reported.
Reported base models: SulphurAI/Sulphur-2-base
Parameter count is not a RAM/VRAM requirement. Check precision, quantization, context length and runtime compatibility in the model card; no hardware or API-cost claim is inferred here.
Use and evaluate
Check license terms and access requirements first. Review the model card’s documented loading instructions, evaluations and safety limitations. Benchmark scores are not imported by this directory, and popularity is not an accuracy ranking.
No model weights are downloaded or executed by AltAPIs. Never enable remote model code without reviewing it.
