Character detail, style fidelity and fast motion stay clear and coherent, while H3's native video+audio generation is fully preserved. In our internal FL2VA evaluation, QuantFunc INT4 vs the BF16 baseline (same prompt, same seed) measures 23.7 dB PSNR. All clips below were generated by MiniMax-H3-QuantFunc-4bit — click a player to watch. On an RTX 4090, 768 × 768, 5s, 124 frames: Prompts, reference images/videos, audio assets and the rest of your workflow nodes stay unchanged. Both weight sets already have the acceleration LoRA, Token Refiner, INT4 Refiner and INT8 Conv Sidecar fused in — no extra components to attach. Runs on every NVIDIA SM75+ GPU: RTX 20/30/40/50-series, A100, H100, H200, B100, B200, GB300. 4-bit weights significantly cut the weight-bandwidth…

Compatibility and lineage
Language coverage was not reported.
Base-model lineage was not included.
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.
