When deploying large models locally, the larger the parameter count, the more VRAM and RAM required; quantized versions (such as 4-bit quantization) can greatly reduce resource usage with a slight loss in quality.

VerifiedQuantization compresses the storage precision of model parameters from 16-bit down to 8-bit or even 4-bit, thereby reducing memory usage, but at the cost of potential loss in model accuracy.77% similarUnverifiedLocally run coding models must account for engineering constraints such as quantization compression, inference speed, and memory footprint, so "laptop-sized" means the model's parameter scale is usually small (hundreds of millions to a few billion).77% similarUnverified模型规模越大，记忆能力反而越强，因为更大的模型拥有更强的参数容量来存储低频样本76% similarUnverifiedFor models with more than 10B parameters, 4-bit quantization can typically reduce memory usage by approximately 50% while keeping capability loss within 5%.75% similarUnverifiedWhen selecting a quantization version, the total available memory (VRAM + system memory) must exceed the requirement stated for that quantization version, with an additional 2–4 GB reserved for the operating system and other processes.75% similar
