As large language models (LLMs) are becoming even bigger, it is increasingly important to provide easy-to-use and efficient deployment paths because the cost of…
However, the reconstruction process of GPTQ leads to an over-fitting issue to the calibration set and may not preserve the generalist abilities of LLMs for other modalities and domains. It also requires a reordering trick to work for some models (e.g., LLaMA-7B and OPT66B). low-bit量化...
Efficient Streaming Language Models with Attention Sinks 韩松实验室发表在ICLR2024上的工作。现在LLM在做的一件事就是追求长度的外推性,即让LLM可以处理足够长的输入序列。作者就是想解决能否在不牺牲效率和性能的情况下,部署一个能处理无限输入的LLM? 作者发现,普通的注意力在处理长序列时计算复杂度和效果都很差...
As you’ll recall, quantization is one of the techniques for reducing the size of a LLM. Quantization achieves this by representing the LLM parameters (e.g. weights) in lower precision formats: from 32-bit floating point (FP32) to 8-bit integer (INT8) or INT4. The tradeoff could be ...
Production ready LLM model compression/quantization toolkit with hw accelerated inference support for both cpu/gpu via HF, vLLM, and SGLang. - ModelCloud/GPTQModel
Quantization reduces the model size compared to its native full-precision version, making it easier to fit large models onto accelerators or GPUs with limited memory usage. This section explains how to perform LLM quantization using GPTQ and bitsandbytes on AMD Instinct hardware. ...
Deploying low-bit quantized LLMs on edge devices often requires dequantizing models to ensure hardware compatibility. However, this approach has two major drawbacks: Performance:Dequantization overhead can result in poor performance, negating the benefits of low-bit quantization. ...
