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).
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.
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.
4 kwi 2024 · 1.58 LLM Experiment Details. Nous Research trained a 1B Bitnet, OLMo-Bitnet-1B on the first 60B tokens of the Dolma dataset. They also trained a standard FP16 OLMo-1B model with the same...
28 lut 2024 · Lingxiao Ma , Lei Wang , Wenhui Wang. , Shaohan Huang , Li Dong , Ruiping Wang , Jilong Xue , Furu Wei. Abstract. Recent research, such as BitNet, is paving the way for a new era of 1-bit Large Language Models (LLMs).
26 mar 2024 · BitNet b1.58 addresses this by halving activation bits, enabling a doubled context length with the same resources, with potential further compression to 4 bits or lower for 1.58-bit LLMs, a...
11 mar 2024 · The resultant values in theory can be represented with 1.58bits by information encoding theory. Since bits can’t be fractional we can represent them in 2 bits. Quantization Function Implementation in Pytorch. Threshold calculation: def compute_adjustment_factor(self, input_tensor: torch.Tensor): absmean_weight = torch.mean(torch.abs(input_tensor))
