UnverifiedQLoRA builds on LoRA by introducing the NF4 (Normal Float 4) 4-bit quantization format, and employs double quantization and a paged optimizer, enabling fine-tuning of a 7B model on a single consumer-grade 24GB RTX 4090 GPU.79% similarUnverifiedSingle-card fine-tuning usually relies on parameter-efficient fine-tuning techniques (such as LoRA); with LoRA fine-tuning of the 1.7B model on a 4-bit quantized base, a single consumer-grade GPU (such as one with 24 GB of VRAM) is sufficient.75% similarVerifiedA 30B parameter model that originally required 60 GB of VRAM can run on consumer-grade GPUs with 16 GB or even 8 GB of VRAM after quantization.75% similarUnverified采用LoRA等参数高效微调技术，需要16GB以上显存72% similar
