As we strive to make models even more accessible to anyone, we decided to collaborate with bitsandbytes again to allow users to run models in 4-bit precision."}, {"text": "This includes a large majority of HF models, in any modality (text, vision, multi-modal, etc.). Users can also train adapters on top of 4bit models leveraging tools from the Hugging Face ecosystem."}, {"text": "This is a new method introduced today in the QLoRA paper by Dettmers et al. The abstract of the paper is as follows:\n\nWe present QLoRA, an efficient finetuning approach that reduces memory usage enough to finetune a 65B parameter model on a single 48GB GPU while preserving full 16-bit finetuning task performance."}, {"text": "QLoRA backpropagates gradients through a frozen, 4-bit quantized pretrained language model into Low Rank Adapters~(LoRA). Our best model family, which we name Guanaco, outperforms all previous openly released models on the Vicuna benchmark, reaching 99.3% of the performance level of ChatGPT while only requiring 24 hours of finetuning on a single GPU."}] |
