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).
BITNET. 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.
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...
9 mar 2024 · log base2(4) = 2, 2 bits can represent 4 values like [0,1,2,3] So, to represent 3 values, log base2(3) = 1.58496350072,i.e approximately 1.58 bits can represent 3 values like [-1,0,1]
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 mar 2024 · Here is the commands to run the evaluation: pip install lm-eval==0.3.0. python eval_ppl.py --hf_path 1bitLLM/bitnet_b1_58-3B --seqlen 2048. python eval_task.py --hf_path 1bitLLM/bitnet_b1_58-3B \. --batch_size 1 \. --tasks \. --output_path result.json \. --num_fewshot 0 \. --ctx_size 2048.
18 wrz 2024 · In the case of 4-bit models, methods that only quantize weights outperform those that quantize both weights and activations, as activations are harder to quantify. However, BitNet, which uses 1.58-bit weights, surpasses both weight-only and weight-and-activation quantization methods.
