What are Large Language Models (LLMs)?

LLMs are advanced AI systems trained on vast datasets using billions of parameters. Built on the transformer architecture, they excel at various language tasks like translation, text generation, and summarization. The ” large ” in LLMs refers to their complex neural networks and extensive training data. These models can produce diverse outputs, including text, images, and videos. Users can access LLM capabilities through user-friendly chat interfaces like ChatGPT or via APIs.

Understanding Chat Interfaces

LLM chat interfaces are suitable for simple day-to-day tasks,  whereas LLM APIs allow developers to integrate these powerful AI tools into applications and services. This dual approach to accessibility has facilitated the widespread adoption of LLM technology across numerous industries and use cases.

Chat interfaces are digital platforms that enable real-time communication between users and systems, often powered by conversational AI or LLMs. They facilitate seamless interaction by allowing users to type or speak their queries, receiving responses instantly. These interfaces range from simple text-based applications, like live support chats, to advanced conversational interfaces in virtual assistants, capable of handling complex, multi-turn interactions and integrating multimedia elements.

In this first series of the article, we will be exploring the various LLMs available through chat interfaces. We will start with proprietary LLMs and then go into open-source LLMs.
