Large Language Models (LLMs) are taking over the world of Artificial Intelligence (AI) and are revolutionizing the way we interact with machines. But what are LLMs and how do they work?
The Basics
A language model is a type of AI that represents human speech. When we speak of "large" language models, we mean models that consist of an enormous number of artificial neurons. These neurons consist of parameters (numbers) that are adapted to the data during the learning process. For example, BERT (2019) had 110 million parameters, GPT-2 (2019) 1.5 billion, and GPT-4, released in 2023, is estimated to have around 1.7 trillion.
Language models are trained to complete texts. In the context of chatbots, for example, this means that they are trained to provide appropriate answers to user queries.
How LLMs process Language
In order to process an input language, the text is first divided into so-called tokens, which roughly correspond to words or parts of words. These tokens are then translated into numbers for the LLM to process.
Like all artificial neural networks, LLMs process data by generating high-dimensional spaces and embedding data there. For example, words that are similar in meaning are placed closely together. This process takes place during training, during which the positions of the data in space can also be adjusted.
Once an LLM is fully trained, the locations of all data - in this case the tokens - are fixed. This is how an AI can store knowledge. However, this requires very large amounts of data.
When we interact with the LLM after training, this is called inference. During this interaction, no further adjustments are made to the LLM and nothing new is learned.
Impact on Practice
Training LLMs and other AI models based on artificial neurons is very difficult. It requires time, high-performance computers, experts who can program the neural network structure and training processes, and most importantly, large amounts of data.
Therefore, the AI industry has started to split the training of LLMs into two phases: pre-training and finetuning. Pre-training refers to general training on large amounts of text to develop a broad understanding of the language. Finetuning is the more specialized training on specific tasks that the AI needs to perform.
Today, in the year 2023, there are language models like ChatGPT-4, Llama-2 and Claude-2 that are so big and have been trained so extensively that they can react flexibly to new requests without further finetuning. Instead, their behavior can be controlled with natural language "prompts". But beware, writing prompts effectively takes practice - otherwise you may not get the desired quality of results.
The Relevance of LLMs to Businesses
Large language models like GPT-4 or Llama-2 and other future models are invaluable for companies. They can take on a variety of tasks that previously required human thought processes. For example, a well-trained LLM can be deployed in customer support to respond to customer inquiries, reducing response times and ensuring a consistently high level of service.
A practical example of this is the company Zendesk, which uses AI-based chatbots to answer customer inquiries and thus optimize customer service. Or OpenAI's ChatGPT, which is capable of composing human-like text and can therefore be used for tasks such as composing emails or other texts.
In addition, LLMs can be used to create content. You can write blog posts, social media posts or product descriptions, saving valuable working time. An example of this is Jasper, an AI-driven content creation tool that helps companies create high-quality content in the shortest possible time.
LLMs can also offer significant added value in the area of data analysis. You can analyze large amounts of data and see complex patterns that the human eye might miss. This enables better business decisions and can provide a competitive advantage.
Overall, LLMs can help businesses operate more efficiently, reduce costs, and provide better customer experiences. Therefore, companies that want to develop or improve their AI strategy should definitely look into the possibilities that LLMs offer.
The Benefits of LLMs for Individuals
Large language models are not only beneficial for companies, private individuals can also benefit significantly from them. Through the ability to understand and respond to human language, LLMs make our everyday lives easier in many ways.
A first example is the use of personal assistants such as Siri, Alexa or Google Assistant, through which users came into contact with LLMs years ago. However, the more recent developments in the past few years have made much more extensive AI assistants possible.
In addition, LLMs can also be used as private tutors. For example, the AI-powered learning platform Squirrel AI uses LLMs to create personalized learning plans and feedback for students, making learning more efficient and personalized.
But LLMs can also support individuals in the creative field. Tools like ShortlyAI use LLMs to help authors create stories. They offer suggestions for storylines or character development and can even compose entire passages.
In addition, LLMs are able to understand and summarize long and complex texts. This makes it easier for individuals to keep track of important information, for example in scientific articles or news reports.
Overall, LLMs can make everyday life a lot easier and help us be more efficient and productive. Given the rapid advances in this field, we can certainly expect many more exciting applications in the future.
Conclusion
Large language models are a fascinating and complex field of AI that has a significant impact on the future of human-machine interaction.
LLMs are a powerful tool companies can use to improve their business processes and gain a competitive advantage. Individuals can also use this technique to their advantage - whether it's for email, research, or even creative endeavors.
However, being able to use these models effectively requires an understanding of how they work and the ability to write effective prompts. However, with the right approach, LLMs can add significant value and help increase efficiency and effectiveness in many aspects of life and business processes.
