Quantization-Aware Healing Recovers 4-Bit LLMs Beyond Full-Precision Performance
Quantization-Aware Healing (QAH) recovers compressed 4-bit models by distilling directly from the original full-scale teacher rather than intermediate checkpoints. Applied to a GPT-OSS 120B model compressed to 60B in MXFP4, it outperforms its own 16-bit bfloat16 source on 7 out of 9 benchmarks.
