ptd/ptd_h3_4step_int8.safetensors and ptd/ptd_h3_ref2va_4step_int8.safetensors, by Nynxz.
Modified from the two PTD releases below: the fl2va file converted from the released training
checkpoint to ComfyUI safetensors, and in both the adapter factors quantized to int8 with one
float32 scale per row. Model Derivatives of MiniMax H3, distributed under the MiniMax H3

Modifications
The files in this repository were modified by WAS (WAS Node Suite) in 2026. Each one is one of
the int8 PTD four-step files above, with a Pika H3 Flex adapter stored once as a shared section
applied at strength 0.5. The tensors of both sources are otherwise unchanged. Each file's
safetensors metadata records both sources by name and SHA-256.
