Hugging Face 宣布與 bitsandbytes 合作，將 4-bit 量化技術直接整合至 Transformers 庫中，並支援全新的 QLoRA 微調方法。這項技術透過 NF4 格式、雙重量化與分頁優化器，大幅降低顯存需求，使 65B 參數模型能在單張 48GB GPU 上進行微調，且幾乎不損失精度。這為資源有限的開發者與研究人員開啟了本地部署與客製化大模型的大門。
This official Hugging Face blog post introduces a deep integration with the `bitsandbytes` library, formally adding 4-bit quantization support to `transformers`, and provides a detailed breakdown of what was then a revolutionary fine-tuning technique — QLoRA (Quantized Low-Rank Adapter).
