SpQR: Sparse-Quantized Representation for Near-Lossless LLM Compression
The "SPQRAlive" tag likely refers to a specific version or variant in a production pipeline (potentially version 18) optimized for "live" or real-time inference environments. These variants often include:
SpQR represents a shift from uniform quantization to . By treating weights differently based on their importance, it bridges the gap between massive model scales and accessible hardware.
: It uses a Hessian-based regularizer to identify which weights are most sensitive to quantization.
: It enables models like LLaMA-65B to fit on a single 24GB or 32GB GPU while maintaining performance.
: The final model is a combination of a dense, low-bit matrix and a sparse, high-precision matrix. 3. Key Performance Metrics
