Quantization-Aware Healing: a compressed, 4-bit model that outperforms its full-precision original

Multiverse Computing publishes a blog post describing Quantization-Aware Healing, a technique to recover compressed 4-bit LLMs. The method reportedly allows a quantized model to outperform its full-precision original on several benchmarks. However, the source describes a research paper and methodology rather than releasing usable model weights or an installable tool for developers.
