    What is a Large Language Model (LLM)?

    Large Language Model (LLM) is a technology that processes human language through data and emulates it. The idea behind an LLM is to create as much human-like content and responses as possible.

    The LLM learns any human language by parsing through a ton of data. This data can be provided through a website, PDF, doc, databases, wikis or other documents. To utilize the power of an LLM, a chatbot is required that can receive queries and answer them appropriately.

    Use Cases of LLM

    There are plenty of use cases for LLM when it comes to businesses. Let’s first start with the use cases that you can use for any business and then address some unique use cases for different industries.

    First, let’s start with the use cases that are applicable to most industries, as opposed to the industry specific ones.

    Use Cases of LLM For All Businesses

    Below are some of the use cases that are applicable for all businesses in different industries.
