LLM, 1-bit

1-bit LLMs are an advanced type of Large Language Model. Unlike traditional LLMs that use 16 or 32 bits for each weight parameter, a 1-bit LLM drastically reduces the model's memory footprint and computational demands, making it faster and more environmentally friendly to run than traditional language models. 1-bit LLMs achieve remarkable efficiency without sacrificing performance by representing the majority of its knowledge with a simplified code using only the values -1, 0, or 1.

BitNet b1.58

One of the latest advancements in natural language processing is the BitNet b1.58 model, a new 1-bit Large Language Model (LLM). This model uses an average of 1.58 bits per weight. It sets the stage for training new generations of LLMs that are high-performing and cost-effective, revolutionizing the field.

The BitNet b1.58 model has demonstrated superior performance on various end tasks while matching the full-precision Transformer LLMs in terms of perplexity and end-task performance. The key advantage of the 1.58-bit LLMs is their efficiency, as they significantly reduce latency, memory, throughput, and energy consumption compared to their full-precision counterparts.

The BitNet b1.58 model also introduces a new computation paradigm that requires almost no multiplication operations for matrix multiplication. This can significantly improve throughput and energy consumption compared to traditional models, making it particularly suitable for non-GPU devices commonly found in edge and mobile devices.
