14/04: uploaded fp8mixed an nvfp4mixed of LTX 2.3 distilled 1.1 16/03: Lightricks released an official dev nvfp4 and distilled fp8 09/03: all formats of both dev & distilled in nvfp4, nvfp4mixed, fp8, and fp8mixed done. 07/03: ⚠️ make sure your torch ( =2.10) & cuda ( =13.0) are up to date, otherwise you won't see a speed boost using nvfp4, may even be slower ⚠️ 05/03: Lightricks released an official dev fp8, probably better to use it instead of mine. Various formats of LTX 2.3, all created from official BF16 versions. Made with Silveroxides/convert to quant script: fp8mixed fp8 nvfp4mixed nvfp4 non calibrated / nc: direct conversion without SVD optimization mixed: keep some weights in native format (embeddings, norm, bias, etc), same exclusion strategy as Lightricks run time config: Windows 11, Nvidia 5090, torch2.10+cu130, SageAttention2.2 8 steps, CFG 1 default sampler/scheduler 960 x 544p, 121 frames, 24 fps x2 spatial upscale 4 refining steps format distilled dev + distill lora nvfp4 54s 57s nvfp4 mixed 57s 59s fp8 (mine) 61s 61s fp8 (Lightricks) TODO 63s bf16 87s 91s Hot run, prompt already processed. Smaller formats look a bit "fuzzy" around the edges in the outputs, but mot…
