Feeling overwhelmed by AI jargon and countless models? You’re not alone. Understanding the best large language models in 2024 is easier than you might think. Thanks to recent advances in multimodal models, AI can now do more than just process text—it can also understand images, sounds, and other forms of data. In this blog, we’ll explore the top 8 LLMs shaping natural language processing (NLP) and help you decide which one to work with:

  • GPT-4o

  • Google Gemini

  • Llama 3.1

  • Claude 3

  • Phi-2

  • Mistral Large 2

  • Gemma

  • OLMo

But first, let’s break down what large language models are and why they matter to you.

Key Takeaways

  • AI can now process not only text but also images, sounds, and other data types, making large language models more versatile.

  • Each model's strengths and weaknesses are discussed to aid in making informed decisions about which one to use.

  • Significant advancements in natural language processing driven by transformer-based neural networks are highlighted.

  • The evolution of generative AI and the crucial role of large language models in various industries are emphasized.

What are large language models?#

A large language model is a transformer-based neural network trained on vast amounts of textual data to understand and generate human-like language. These LLMs can perform various NLP tasks, such as text generation, translation, summarization, sentiment analysis, etc. In recent developments, some LLMs have even evolved beyond simple text generation and now work with multimodal data, handling both text and other forms like images and audio. This progression marks a significant shift in generative AI with large language models.

A transformer is at the heart of large language models, like a machine that pays close attention to all the words in a sentence and figures out how they relate. It does this using a clever trick called self-attention—basically, it looks at each word and checks how important every other word is to understanding it. A basic transformer has two main parts: an encoder and a decoder. The encoder takes in the information (like a sentence), and the decoder spits the answer (like a new sentence). The encoder and decoder use layers of simple feed-forward networks to pass the information through.

Here’s the cool part: with multihead self-attention, the transformer doesn’t just look at one relationship between words—it looks at many at once, like examining the sentence from different angles. This lets the model understand complex meanings and generate text that makes sense.

Note: Not all large language models use an encoder and a decoder. For instance, decoder-only models like GPT-4o are optimized for generating human-like text based purely on input prompts.

A basic transformer-based model consisting of an encoder and decoder is shown below:

Architecture of vanilla transformer where the left side is an encoder responsible for handling the input and the right side is a decoder to generate the output
Architecture of vanilla transformer where the left side is an encoder responsible for handling the input and the right side is a decoder to generate the output

In such a model, the encoder is responsible for processing the given input, and the decoder generates the desired output. Each encoder and decoder side consists of a stack of feed-forward neural networks. The multi-head self-attention helps the transformers retain the context and generate relevant output.

The “large” in large language model refers to the massive scale of training data and the number of parameters involved. These models are trained on billions of words and sentences sourced from books, articles, websites, and other textual data. With millions to billions of parameters, LLMs capture complex linguistic patterns and relationships, making them powerful tools for diverse NLP tasks.

Training LLMs begins with gathering a diverse dataset from sources like books, articles, and websites, ensuring broad coverage of topics for better generalization. After preprocessing, an appropriate model like a transformer is chosen for its capability to process contextually longer texts. Training and fine-tuning follow afterward. This iterative process of data preparation, model training, and fine-tuning ensures LLMs achieve high performance across various natural language processing tasks.

Top 8 LLMs in 2024#

Let’s explore these top 8 language models influencing NLP in 2024 one by one.

1. GPT-4o#

First,  talk about GPT-4o, the latest and most advanced model from OpenAI. The “o” stands for “omni,” which is a fancy way of saying it can handle pretty much anything you throw at it—text, audio, images, and even video. It’s a big leap from the earlier GPT-4 and GPT-3.5-turbo, which mainly used text and images. GPT-4o can input all these input types and spit out text, sound, and pictures as output. Pretty neat, right?

However, here’s where it gets really interesting: GPT-4o is fast. It can respond to audio in just 232 milliseconds according to OpenAI benchmarks, which is almost as quick as you can respond in a real conversation, perhaps even more! That makes the whole interaction feel a lot more natural. It’s also better at handling languages other than English, and when it comes to understanding images and sound, it’s way ahead of the other models out there currently.

Of course, GPT-4o still has its quirks. Like the older models, it can sometimes hallucinate—meaning it makes up facts or mixes up names. You might ask it something about Elvis Presley, and it might give you information about Elvis Costello instead. But even with those hiccups, GPT-4o is one of the most powerful and versatile models, especially when handling multimodal tasks involving more than just plain text.

2. Gemini#

Gemini is a multimodal LLM developed by Google and competes with others’ state-of-the-art performance in 30 out of 32 benchmarks. Its capabilities include image, audio, video, and text understanding. The Gemini family includes Ultra (175 billion parameters), Pro (50 billion parameters), and Nano (10 billion parameters) versions, catering various complex reasoning tasks to memory-constrained on-device use cases. One standout feature is Gemini’s ability to handle context windows up to 32k tokens, allowing it to efficiently manage long and complex inputs. It’s built on transformer architecture and uses multi-query attentionMulti-query attention is an optimization in Transformer models that shares key and value projections across heads, improving efficiency while maintaining separate query projections., enabling it to process text alongside audio and visual inputs and even generate text and image outputs.

Gemini’s performance often surpasses GPT models, largely due to Google’s immense computational resources and access to vast datasets. Notably, Gemini also supports video input, a capability that most of the GPT models, apart from GPT-4o, lacked, making it more powerful for tasks requiring cross-modal reasoning.

For example, consider this physics problem shown in the illustration below. A teacher drew a question on the left, and Gemini analyzed the student’s incorrect solution and explained the correct answer, identifying the errors and formatting the response in LaTeX for mathematical clarity.
