The HyperFlow H3 Flash weights in this repository are a Model Derivative of MiniMax-H3
(https://huggingface.co/MiniMaxAI/MiniMax-H3) as defined in Section I.11 of that Agreement. Video Rebirth created
them (Copyright 2026 Video Rebirth, https://huggingface.co/VideoRebirthAI/hyperflow-h3-flash) and distributes them
under the same Agreement. This repository redistributes them under that Agreement with no additional terms. A copy of

Modifications from Video Rebirth's release (Section III.2), in
diffusion_models/minimax_h3_fl2va_hyperflow_flash_int8_convrot_comfy.safetensors (from fl2va_int8_convrot/) and
diffusion_models/minimax_h3_ref2va_hyperflow_flash_int8_convrot_comfy.safetensors (from ref2va_int8_convrot/):
- Converted from the diffusers layout to ComfyUI's int8_tensorwise + convrot layout. The int8 values and per-row
  scales are copied unchanged; no weights were retrained or requantized.
- Tensors are renamed to ComfyUI's MiniMax H3 names, q/k/v rows are concatenated, and blocks after the dropped blocks
  are renumbered.
- The two halves of each SwiGLU fc1 projection are swapped to put the gate first.
- Low-rank pairs are kept in bf16 with their rank zero-padded to a multiple of 256, which leaves their product
  unchanged.
- Every converted tensor was checked against Video Rebirth's Q8_0 GGUF of the same weights.
