PyTorch Implementation of the linear methods and model from the paper "BitNet: Scaling 1-bit Transformers for Large Language Models". Paper link: BitLinear = tensor -> layernorm -> Binarize -> abs max quantization -> dequant.
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).
27 kwi 2024 · BitNet. PyTorch Implementation of the linear methods and model from the paper "BitNet: Scaling 1-bit Transformers for Large Language Models". Paper link: BitLinear = tensor -> layernorm -> Binarize -> abs max quantization -> dequant. "The implementation of the BitNet architecture is quite simple, requiring only the replacement of linear ...
This repository introduces a toy work-in-progress implementation of BitNet - a scalable and stable 1-bit Transformer architecture designed specifically for large language models. Key Features BitLinear: BitNet introduces BitLinear, a drop-in replacement for the nn.Linear layer in PyTorch.
17 paź 2023 · In this work, we introduce BitNet, a scalable and stable 1-bit Transformer architecture designed for large language models. Specifically, we introduce BitLinear as a drop-in replacement of the this http URL layer in order to train 1-bit weights from scratch.
BitNet replaces traditional Linear layers in Multi-Head Attention and Feed-Forward Networks with specialized layers called BitLinear with ternary (or binary in the older version) precision. The BitLinear layers introduced here quantize the weights using ternary precision (with values of -1, 0, and 1) and quantize the activations to 8-bit precision.
1 mar 2024 · Operation with 1-bit Technology. BitNet 1.58 B utilizes 1-bit technology, enabling it to process with parameters set to -1, 0, or 1. This approach reduces the computational complexity, diverging...
