12 Best Large Language Models (LLMs) in 2024

In today’s world, Large language models are highly advanced programs that help machines understand and generate Human-like text. They have been the foundation of Natural language processing for almost 10 years now.

Although artificial intelligence ( AI ) has gained popularity recently, large language models ( LLM ) started to appear around 2014 after the discovery of the publication of a research paper “Neural Machine Translation by Jointly Learning to Align and Translate.”

So what are LLMs? Well, Large language models ( LLM ) are a type of language model that is known for their ability to understand general-purpose language and generation. LLM gets these abilities by using data to learn and train on billions of parameters which also consume large amounts of computational resources during the process. LLMs are basically Artificial neural networks otherwise well known as transformers and are pre-trained using methods like self-supervised learning and semi-supervised learning.

After the Discovery of the publication, LLM has seen a giant boost in research and development over the years with LLMs like ChatGPT from OpenAI, Bard from Google, PaLM, Claude, Cohere, Flacon, LLaMA by Meta, Guanaco, MPT, Lazarus and many more emerging today. Some of them are open source while others are closed source from large corporations such as Google, Microsoft, X formally known as Twitter, ChatGPT by OpenAI, and many more.

In this article, we will dive deep into the best LLM currently accessible and why they have an edge over others.

12 Best Large Language Models ( LLMs ) in 2023
