DuoGPT: Training-free Dual Sparsity through Activation-aware Pruning in LLMs

NeurIPS 2025poster

Large language models (LLMs) deliver strong performance but are difficult to deploy due to high memory and compute costs. While pruning reduces these demands, most methods ignore activation sparsity observed at runtime. We reinterpret activation sparsity as dynamic structured weight sparsity and pro…

GPTAQ: Efficient Finetuning-Free Quantization for Asymmetric Calibration

ICML 2025poster

We introduce GPTAQ, a novel finetuning-free quantization method for compressing large-scale transformer architectures. Unlike the previous GPTQ method, which independently calibrates each layer, we always match the quantized layer's output to the exact output in the full-precision model, resulting i…
