Minimax H3 INT8/INT4 Convrot Just uploaded both FL2VA &amp; REF2VA w4a8_mixed models quantized by Kijai. True int4 model size with int8 activations, near int8 quality, same speed as int8. For RAM-constrained systems. Update your ComfyUI to the latest version for support of the new w4a8 (Should be included in Stable ComfyUI v0.31.0 <a target="_blank" rel="ugc" href="https://github.com/Comfy-Org/ComfyUI/pull/15308">https://github.com/Comfy-Org/ComfyUI/pull/15308</a> FL2VA - first last (frame) to video / audio REF2VA - ref_images / ref_videos / ref_video_audios / ref_audios: up to 9 reference images, 3 reference videos (each may carry its own paired soundtrack), and 3 standalone reference audio clips Both models can generate t2v (Text to video), i2v (Image to video), v2v (Video to Video), a2v (Audio to video), and multiple references (image/video/audio). But were further fine-tuned/trained for higher-quality outputs for the intended use. 14.81 GB INT4BQ Balanced-Quality leaning: int8_ratio 0.41 by count, 0.47 by params; int8mm_ratio 0.5817.27 GB INT4Q Quality: int8_ratio 0.73 by count, 0.75 by params; int8mm_ratio 0.27

lightx2v_4step_turbo_v0.1+ rank21 version (300mb) uploaded; works with pruned/non-pruned Best settings (WIP): 5-8 steps er_sde/res_multistep simple. Strength 0.75 seems to be the best (0.5-0.8) New larryvrh 850ckpt uploaded. Update to the latest comfyui commit as the audio with low steps should be improved, Which is what ive been running with the examples posted <a target="_blank" rel="ugc" href="https://github.com/Comfy-Org/ComfyUI/commit/bdcb886a4705a03cf40f4a7226de9fc7c059fc90">https://github.com/Comfy-Org/ComfyUI/commit/bdcb886a4705a03cf40f4a7226de9fc7c059fc90</a> If you are still running into bad audio here is the loras larryvrh custom node <a target="_blank" rel="ugc" href="https://github.com/Larryvrh/ComfyUI-MiniMax-H3-Turbo">https://github.com/Larryvrh/ComfyUI-MiniMax-H3-Turbo</a> This LoRA is an early version of a training run currently underway that larryvrh is doing. Degrades audio quality at 4 steps. Best used at 6-8 steps res_multistep + simple Using 850ckpt for anime and 500ckpt for realism works best Examples are generated with 1.0I did not train, distill or create the original Turbo LoRA weights. This model page only provides modified compatibility versions intended to allow the remaining compatible LoRA adapters to load with ComfyUI's built-in LoRA loader when using the pruned/curve-form model.
