Last Updated: July 29, 2024

Large language models (LLMs) are a type of generative AI that specializes in processing and producing human-like text based on vast amounts of training data and complex neural network architectures. LLMs are a hot topic, with more than 5,000 academic publications discussing them since 2017.

LLMs power popular AI chatbots such as ChatGPT and Claude.

As we described in our explanation of generative AI, think of a parrot, only unimaginably sophisticated. Where a parrot learns to repeat phrases, LLMs learn the underlying patterns of language. They don’t actually “understand”; they’re just incredibly good at learning and repeating patterns.

This pattern-matching ability unlocks some pretty awesome use cases for LLMs, which we’ll explore.

Main takeaways
LLMs amplify human abilities across a wide range of disciplines.
To date, LLMs are no substitute for human judgment and creativity.
LLMs have some pretty glaring shortcomings.
Humans who leverage LLMs will outcompete their peers across most knowledge tasks.
We show you how to make the most of LLMs while minimizing their downsides.

How do LLMs work?

Let's take a closer look at how LLMs work under the hood. While the details can get complex, here's a simplified overview of the main components or aspects:

  1. Model design. LLMs use a structure called a transformer. This architecture includes attention mechanisms that help the model understand how words relate to each other in sentences, leading to more natural and coherent text generation.
  2. Neural networks. LLMs rely on artificial neural networks that mimic the human brain's structure, with interconnected nodes that process and transmit information. The transformer is a specific type of neural network architecture that excels at handling sequential data, such as text.
  3. Training process. The model is trained on massive datasets, usually text content. They learn from both the structure and content. Backpropagation adjusts the weights of the neural network to improve the model's ability to predict and generate language. Over time, the model becomes better at understanding context and generating relevant text.
  4. Specialization. After the initial training, LLMs can be fine-tuned on specific types of text to excel at particular tasks, such as customer service, legal analysis, or medical advice. This fine-tuning process helps the model adapt to specialized vocabularies and contexts.
  5. Practical use. Once ready, LLMs can tackle many different tasks. They analyze input, apply what they've learned, and produce relevant text—whether answering questions, translating, or creating content.

Types of large language models

LLMs are a recent outshoot of the fields of natural language processing (NLP) and AI. They can understand, generate, and manipulate human language in ways that were previously unimaginable. While there are many LLMs available, they generally fall into the following categories based on their architecture, training data, and use cases.

  1. Transformer models
  2. Autoregressive models
  3. Encoder-decoder models
  4. Multimodal models
  5. Specialized domain models

Transformer-based models

In 2017, a group of researchers introduced the transformer architecture, and it turned the natural language processing world upside down. Here's why: instead of processing words one after another like a slow reader, transformer models look at all the words in a sentence at once. This parallel processing helps the model grasp context much better, like understanding that "bank" means something different in "the river overflowed its bank" versus "I set up my bank account " versus “bank the airplane.”

Autoregressive models

Picture a word-guessing game where you predict the next word based on what came before. That's how autoregressive models work. They excel at text generation tasks, churning out human-like text that can range from a few sentences to entire paragraphs or even stories.

Encoder-decoder models

Encoder-decoder models take in one form of text (the input sequence) and flip it into another (the output sequence). This makes them perfect for tasks such as translating "Hello, how are you?" into "Bonjour, comment allez-vous?" or condensing a long article into a brief summary.

Multimodal models

Multimodal models can work with texts, images, audio, and even video. As AI applications grow more complex, these versatile models become increasingly important. An AI that can describe what's in a photo, transcribe a podcast, and then summarize it all in a neat paragraph uses multimodal models.

Specialized domain models

Specialized domain models focus on specific industries or tasks, using domain-specific data to boost their performance. For example, a model trained on medical literature will likely outperform a general-purpose model when it comes to analyzing patient symptoms or suggesting treatment options.
