Fizgig v5.0 enables full fine-tuning of MiniMax H3 and Krea 2 base models on consumer GPUs with as little as 16GB VRAM. The technique uses a rotating window for trainable slices, 4-bit frozen weights, and system RAM for the master weights. It also includes a tool to diff the full checkpoint into a shareable LoRA.
