bitnet.cpp is the official inference framework for 1-bit LLMs (e.g., BitNet b1.58). It offers a suite of optimized kernels, that support fast and lossless inference of 1.58-bit models on CPU (with NPU and GPU support coming next).
18 wrz 2024 · BitNet is a special transformers architecture that represents each parameter with only three values: (-1, 0, 1), offering a extreme quantization of just 1.58 ( l o g 2 (3) log_2(3) l o g 2 (3)) bits per parameter. However, it requires to train a model from scratch.
This repository not only provides PyTorch implementations for training and evaluating 1.58-bit neural networks but also includes a unique integration where the experiments conducted automatically update a LaTeX-generated paper.
9 mar 2024 · The basic formula for this is shown as, x_q = round (x/S + Z) x: The original continuous variable that we want to quantize. x_q : The quantized value of x. S: The scaling factor. This...
28 lut 2024 · Recent research, such as BitNet, is paving the way for a new era of 1-bit Large Language Models (LLMs). In this work, we introduce a 1-bit LLM variant, namely BitNet b1.58, in which every single parameter (or weight) of the LLM is ternary {-1, 0, 1}.
29 lut 2024 · Unlike its predecessors, BitNet b1.58 is trained from the ground up, utilizing weights quantized to 1.58-bits and activations reduced to 8-bits. This approach significantly deviates from the standard full-precision formats typically seen in AI models.
26 mar 2024 · 1-Bit LLMs: 1-bit LLMs, or 1-bit Large Language Models, represent a groundbreaking approach to tackling the challenges posed by the immense size of traditional LLMs. In essence, these models...
