PotatoForge/Minimax-H3-Image-W4A4

MiniMax-H3-Image — W4A4

An experimental W4A4 quantization of MiniMax-H3-Image, created using PotatoForge.

This quantization was produced from the BF16 checkpoint published by Comfy-Org.

Why W4A4?

On my GTX 1660 Super (6 GB), W4A8 inference was nearly 4× slower, which motivated this W4A4 release.

The goal is to improve inference performance on older, resource-constrained GPUs while maintaining reasonable image quality (reasonable for an int4 quant).
