2-bit quantization represents each parameter with 2 binary bits, achieving an 8x compression ratio compared to FP16, making it the highest compression tier among currently practical quantization methods, and it is generally only suitable for large-parameter models with redundant structures such as MoE

UnverifiedTraditional 8-bit quantization can only achieve approximately 2x compression.76% similarUnverifiedTernary representation theoretically requires only about 1.58 bits per parameter, which can yield nearly a 10x storage compression compared to FP16.74% similarUnverifiedOn-device large models compress parameter counts to the 1B–7B level through techniques such as model quantization (compressing FP32 to INT4/INT8), knowledge distillation, and structural pruning, enabling real-time inference on local chips.71% similarUnverifiedQuantization 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.71% similarVerified4-bit quantization in GGUF format can compress model weights from 32-bit floating point to 4-bit integers, reducing model size by approximately 8 times.70% similar
