The 1 Bit LLM is a new innovative way of training and performing inference on an LLM Model through the process of quantization proposed by Microsoft. In this blog article, we will be breaking down how and why exactly this usage of very small bits for training and inference of LLM Models is a huge boon moving forward for the LLM eco-system as a whole.

## Why do we need this?

First off, let's understand the purpose and the why behind this new innovative way of building and training LLMs.

In the case of a 1-bit LLM, we mainly focus on reducing the weights required to train an LLM model from a huge floating point number to bits in general. This can help provide extremely fast inference aka model outputs along with very low amounts of storage costs.

Traditionally, LLM Models are extremely bloated and take a while depending on their context length of course to perform inference and provide an output to the end user. And, the main problem over here is the huge amounts of floating point values used for the weights of the LLM Model which can prove to be taxing both to perform inference on and to store as well and this is where this new innovative strategy of using 1 Bit LLMs tends to shine.

Now, The 1 Bit LLM models in general have ternary weights ``{-1,0,1}`` as opposed to the traditional LLM Models that have weights in the floating point range which are in general much more computationally taxing to both store and perform inference on. Now, why is this model magic? Due to the fact that we drop the weights, we are essentially gaining a speed boost and memory boost of over 1.5-2x in general at least as per the benchmarks released by Microsoft without any drop in the quality of the output results received from the LLM Model after inference. We will also be exploring how exactly it manages to reduce the amount of performance needs it has while maintaining the quality of the results as compared to a traditional LLM in this blog.

Now, Why is this magical? This model when compared to the traditional LLM Models which require a lot of both GPUs and electricity does not need as much. Due to its inherent nature of being able to work with low quantity weights in contrast to traditional LLMs, a 1 Bit-LLM can provide wings to both individual developers or resource-constrained companies due to the fact that it can be trained and can also perform inference even using a limited set of compute / GPU resources. 

This would also be very beneficial to society due to how much energy ChatGPT and other LLM Models alike, in general, tend to consume and would also solve the problems of modern LLMs becoming [thirsty](https://www.firstpost.com/tech/news-analysis/thirsty-ai-microsoft-majorly-disrupted-us-citys-water-supply-to-develop-chatgpt-bard-causing-a-crisis-13109242.html) in nature thus preserving energy on a global scale as well and not causing harm to the natural resources.

## Introduction

Now, we will be discussing the origins of this model. This model was released by Microsoft and the company's 1 Bit LLM Model variant is called the ``BitNet b1.58`` model which is currently in its [research](https://huggingface.co/papers/2402.17764) stages with it not being released yet however stay tuned as it can show up any time soon. 
This model has been mainly created to optimize the amount of memory resources and the time taken to both train and get the output of an LLM Model and has been created as a solution to the large amounts of computing traditional LLM Models tend to require in general through the use of very small value of the weights used in general for LLMs. 

This model only uses the ternary weights/parameters with the values ``{-1,0,1}`` as compared to traditional LLM Models that use 8 or 16-bit values which are in the floating point range and are generally computationally expensive to compute and get the inference.

This model is mainly based on the BitNet Architecture and The core of this advancement is the 1-bit quantization technique, where each parameter in the model, known as weights, is encoded using only 1.58 bits. Unlike conventional LLMs that typically use 16-bit floating-point values (FP16) for weights, the 1-bit LLM confines each weight to one of three values: -1, 0, or 1. 
This reduction in bit utilization is a fundamental aspect of the model.

This technology marks a departure from traditional 8-bit storage, offering a single parameter storage of only 1.58 bits. Such improvements are anticipated to enhance training compute performance and speed, with potential applications in bolstering edge AI. The introduction of 1-Bit LLM technology is seen as a technological breakthrough that could significantly impact the future of AI systems and their deployment across various industries.

The BitNet b1.58 model introduces a compelling alternative to traditional LLM architectures, providing a blend of high efficiency, reduced computational cost, and maintained performance. It pushes the boundaries of creating more energy-efficient models, addressing a critical concern in deploying sizable LLMs. The diminished resource requirements potentially lower the barrier to deploying advanced NLP capabilities on edge and mobile devices, broadening the application horizon of LLMs. Furthermore, it opens avenues for designing specialized hardware optimized for 1.58-bit or ternary architectures, hinting at more cost-efficient AI accelerators in the pipeline.

## Working

Traditional transformer models and the 1-bit LLM Model also perform inference mainly through the process of matrix multiplication and in traditional cases, every single value of the matrix would be in the 8-bit or the 16-bit ranges aka float and sometimes even the double-datatype ranges making the already complicated and slow process of matrix multiplication much more larger. However, the beauty of the 1 Bit LLM Model is its ternary weight.

Due to the usage of these ternary weights, this model will perform matrix multiplication on only values in the range between -1 <= 1 where any value related to zero is dropped as well and all of these are integer values as compared to the previously used floating point values making this model much faster in nature in the process of performing inference and storing these 3 ternary numbers is a very easy task as compared to storing 8-bit or 16-bit numbers in general.

The model's design also incorporates key elements like [RMSNorm](https://arxiv.org/abs/1910.07467) and [SwiGLU](https://paperswithcode.com/method/swiglu), akin to LLaMA, with a specific emphasis on system-level enhancement through a quantization function. This amalgamation and optimization result in accelerated processing speeds and decreased GPU memory usage as compared to the traditional/conventional large language models.

Throughput is another area where BitNet b1.58 excels, offering much higher throughput at a lower maximum batch size compared to traditional models. This improvement in throughput is crucial for handling large datasets and performing multiple operations simultaneously 1.

In summary, the computation in 1-bit LLMs like BitNet b1.58 is characterized by a shift towards integer-based operations, reduced energy consumption, and enhanced memory and latency performance. These advancements not only make the models more efficient but also open up new possibilities for deploying LLMs in resource-constrained environments like edge and mobile devices.

Finally, the reason why the inference process that happens through the matrix multiplication approach in this model is very fast as compared to the traditional LLM Models is because of the presence of "0" in this model. Due to the presence of 0, matrix multiplication which is a combination of first multiplication and addition, remains unaffected for the most part it as this value is ignored in general and the multiplication / addition of -1 or 1 is also not a very costly operation as compared to the multiplication / addition of floating point numbers and this is known as the [Pareto Efficiency](https://en.wikipedia.org/wiki/Pareto_efficiency).

## Quantization Process in the 1-Bit LLM Model


![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/0jn13fbns4zbp3vxfzrz.png)


The quantization process in BitNet b1.58, which replaces floating-point numbers with ternary weights, is a groundbreaking approach that significantly reduces computational requirements while maintaining or improving performance. This process is based on the idea that, in the context of deep learning, we don't need precision at all; we only need three symbols to represent every value, namely ``{-1, 0, 1}``.

The quantization technique involves replacing all parameter floating-point values representing real numbers with ternary values in the matrices used. This is a radical departure from traditional quantization methods, which often aim to reduce the precision of weights to lower bit widths (e.g., 8-bit integers) while still maintaining acceptable accuracy levels. The shift to ternary values is not just about reducing precision but about eliminating it altogether, focusing instead on the sign of the values.

In matrix multiplications, where the bulk of computation in LLMs occurs, the quantization process transforms elementwise products in each dot product (e.g., a₁b₁ + a₂b₂ ...) into elementwise additions (a₁+b₁ + a₂+b₂ ...), where the signs depend on each value. This change is possible because multiplication is not as crucial with ternary values as it is with floating-point numbers. The shift to ternary values allows for the execution of matrix multiplications via cheaper tritwise operations in hardware, which is a more natural fit given the limited range of ternary values.

## Quantization Function used in the 1-Bit LLM Model

The quantization function in BitNet b1.58 is a critical component that enables the model to operate efficiently with significantly reduced computational resources.

This model employs a very special form of quantization function to achieve the required result from the ternary operators. The way this function works is very simple. 

The model. ``BitNet b1.58`` employs an ``absmean`` quantization function that scales and rounds the weight matrices. This function is designed to convert the conventional model weights, which are typically represented in 16-bit floating-point values, to ternary values {-1, 0, 1}. Simply put, we find the closest ternary value to the original 16-bit weights used for the traditional LLM Models. 

This conversion effectively reduces the bits per parameter to 1.58, a key feature that distinguishes BitNet b1.58 from traditional LLMs.

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/m5y1veauxhyq8g4qdqoa.png)

The ``absmean`` function used in the 1-bit LLM model involves calculating the average absolute value of the weights in a weight matrix. Here is a detailed breakdown of how the  function works in the context of this model:

1. **Calculate Absolute Values**: First, the absolute values of all weights in the weight matrix are computed.

2. **Find Average**: The average of these absolute values is then calculated to determine the mean absolute value.

3. **Normalization**: This mean absolute value is used to normalize the weights within a certain range suitable for ternary operators.

4. **Quantization**: After normalization, the weights are quantized to -1, 0, or +1 based on their relationship to this normalized range.

The main core steps of Scaling and Rounding will now be broken down -  

- **Scaling**: It first scales the weights in the 16-bit format to the average absolute value possible thus making the weights to be in that range of the ternary operators.

In case that was too complicated, let's break it down.

We will first be considering a simple neural network layer with weights represented in a 16-bit format. The weights are scaled to the average absolute value possible, which means they are normalized within a certain range. In the 1-bit LLM model, these weights would then be quantized to either -1 or +1.

For instance, if we have a weight matrix like:

```
[[0.5, -0.3],
[-0.8, 0.7]]
```
After scaling aka the first step in the quantization process of the 1-bit LLM model, it might become:

Normalized Weight Matrix:
```
[[0.5/Max_abs_value, -0.3/Max_abs_value],
[-0.8/Max_abs_value, 0.7/Max_abs_value]]
```

where the ``Max_abs_value`` denotes the maximum absolute value among all the weights in the weight matrix

This binary representation simplifies the computations during inference while still allowing the neural network to make predictions effectively.

 - **Rounding** : After scaling, every weight value on the normalized matrix is then rounded off to the nearest integer value among -1, 0, and +1. This translates the scaled weights into the discrete ternary system.

So, in the case of our example, the weights finally becomes,

Normalized Weight Matrix:
```
[[0.5/Max_abs_value, -0.3/Max_abs_value],
[-0.8/Max_abs_value, 0.7/Max_abs_value]]
```

After rounding off the normalized weights, 1-bit LLM model, it might become:

```
[[+1, -1],
[-1, +1]]
```

The implications of this quantization approach are profound. It not only reduces the computational resources required for training and inference but also opens up possibilities for specialized hardware optimized for ternary operations. This could lead to more energy-efficient AI accelerators and a new wave of hardware specifically designed for ternary computations. The shift to ternary weights also aligns with a broader trend towards more efficient and sustainable AI practices, where reducing the bit width of model parameters can lead to significant reductions in energy consumption and computational requirements.

This quantization function is particularly beneficial for BitNet b1.58 because it simplifies the implementation and system-level optimization while introducing negligible performance impacts. It allows for the execution of matrix multiplications via cheaper tritwise operations in hardware, which is a more natural fit given the limited range of ternary values. This approach not only reduces the computational resources required for training and inference but also maintains or even improves the model's performance.

To summarize, the quantization process takes place through the ``absmean`` quantization function which proves to be crucial for the conversion of the 16/8-bit floating point values to the ternary operator values that this model can perform matrix multiplication. 


## Why does it specifically use 1.58?

Now, you must be wondering why it's called the ``BitNet b1.58`` model and we will now be exploring the significance of this specific number used. 

The "1.58" in the name BitNet b1.58 refers to the average bits per parameter used in the model, which is calculated by considering the three possible values (-1, 0, +1) and the fact that one of these values (0) is a placeholder for zero causes the value to increase from 1 to 1.58 bits. 

And, in case it wasn't clear, the 1.58 bits per parameter signifies the effective bit width used to represent the weights in the model, compared to the 16 bits used in traditional LLMs. This naming highlights the model's efficiency and the innovative approach to reducing the computational resources required for training and inference without compromising performance.

## Key Elements of the 1-Bit LLM Model


![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/2d1fxotfhwukv3x28v3d.png)


Now, let's circle back and understand the key elements of this model other than the quantization function and more.

The BitNet b1.58 model, a pioneering 1-bit Large Language Model (LLM), integrates several key components and architectural adjustments to achieve significant reductions in computational requirements while maintaining or even improving performance. These elements/components, which are similar to those found in the LLaMA model architecture, include:

1. **RMSNorm**: This is a normalization technique used to stabilize the training process. It works by normalizing the activations of each layer to have zero mean and unit variance, which can help stabilize the learning process and prevent vanishing or exploding gradients. This normalization method is crucial for training deep neural networks effectively.

2. **SwiGLU**: SwiGLU is an activation function that offers efficiency advantages over traditional activation functions like ReLU or GELU. It's designed to be more computationally efficient, especially in the context of 1-bit LLMs where computational resources are limited. SwiGLU is particularly effective in reducing the number of multiplication operations required during the forward and backward passes of the model, contributing to the model's overall efficiency.

3. **Rotary Embeddings**: This method is used for representing words and positions within the model. Rotary embeddings introduce a circular, or rotary, pattern into the model, which can be particularly useful for tasks that require understanding the order or position of words, such as translation or summarization. By incorporating rotary embeddings, BitNet b1.58 can more effectively capture the sequential nature of language.

4. **Removal of Biases**: In traditional LLMs, bias terms are often used to adjust the output of neurons, but in BitNet b1.58, these bias terms are removed. This simplification of the model architecture can lead to further reductions in computational complexity and memory usage, contributing to the model's efficiency.

## Capability to handle long sequences of text

The BitNet b1.58 model, in particular, matches the performance of full-precision (FP16 or BF16) Transformer LLMs in terms of perplexity and end-task performance, while being significantly more cost-effective in terms of latency, memory, throughput, and energy consumption. This model represents a new scaling law and recipe for training high-performance and cost-effective LLMs. The introduction of 1-bit LLMs opens the door for designing specific hardware optimized for these models, potentially enabling their deployment on edge devices with limited resources.

One of the key advantages of 1-bit LLMs is their ability to handle long sequences of text with the same memory budget as shorter sequences. This is achieved through BitNet's compressed activations, which allow for the handling of double the sequence length for the same memory budget, bringing native support for long text comprehension within reach. This feature is particularly beneficial for applications that require processing large volumes of text, such as document summarization, long-form conversational agents, and comprehensive question-answering systems.

Moreover, the 1-bit LLMs' reduced computational demands and memory requirements open up new possibilities for deploying AI models on consumer devices, potentially making sophisticated AI assistants more accessible and affordable. This could lead to a democratization of AI technology, where powerful dialog agents can operate on everyday devices, reducing reliance on cloud services and offering privacy benefits by processing conversational data locally.
