Large Language Models, or LLMs, are advanced computer programs that mimic human-like understanding and generation of text. Recently, open source LLMs have gained popularity, offering the freedom to use, modify, and enhance them, fostering innovation and wider accessibility. 

This article talks about the top open-source LLMs of 2024, showcasing their key features and benefits. It aims to guide you in choosing the right LLM, ensuring you the right decisions about integrating these powerful tools into your projects or research.

What is an LLM?

Large Language Models (LLMs) are advanced artificial intelligence systems designed to understand and generate human-like text. These models are trained on vast amounts of text data, enabling them to recognize patterns, grasp language nuances, and produce coherent, contextually relevant text. At their core, LLMs use a technique known as deep learning, where they process and analyze data through layers of artificial neural networks, mimicking the way human brains operate.

Primary role of LLMs in natural language processing (NLP):

• Facilitate interactions between computers and humans using natural language. They can understand user queries, interpret the context, and generate responses that are not only relevant but also sound natural. 
• For instance, virtual assistants like Siri and Alexa leverage LLMs to understand spoken commands and provide accurate responses. In content creation, these models assist in drafting articles, generating creative stories, and even composing music or poetry. In the customer service domain, LLMs power chatbots that handle inquiries, offering instant and efficient assistance to users.
• LLMs are instrumental in translating languages, summarizing lengthy documents, and even driving research by sifting through extensive scientific literature to find relevant information.
