Partially VerifiedTaking the 65B-parameter LLaMA model as an example, traditional full fine-tuning requires more than 780GB of VRAM, whereas QLoRA requires only approximately 48GB.79% similarUnverifiedWith 64 GB of memory, models with 30B to 34B parameters can run smoothly under Q4 quantization, while a 70B model is barely feasible under Q4 but with a noticeably slower response speed.79% similarVerifiedQLoRA introduces 4-bit quantization technology, making it possible to fine-tune models with 65 billion parameters on a single RTX 3090/4090 GPU with 24 GB of VRAM.78% similar
