Overview

ICQuant demonstrates improved outlier suppression in low-bit quantization, enhancing model accuracy significantly.

Key Points

  • ICQuant improves quantization quality while reducing bit overhead to 0.3 bits, a significant saving.
  • Using ICQuant, zero-shot accuracy of the Llama3-70B model improves by up to 150% relative to existing methods.
  • The framework efficiently targets outliers, minimizing their impact on quantization range and errors.
  • ICQuant can be integrated with existing quantizers, supporting better performance without requiring extensive fine-tuning.
