**What is Generative AI ?**

For the given user input(user query), output like text,image, video etc will be generated. This is called generative AI.

**How it generates content?**

A model will be used to generate output. i.e model will receive input and based on that, it will generate a output.

**What is a model?**

At its core, model is nothing but a mathematical equation.It will be multidimensional. vast amount of multimodal data (text,audio,video, image etc) would be subjected to training to get the required mathematical equation. To get the desired state, backpropagation will be carried out.

120b model means, equation has, 120 billion parameters. One of the commonly used model type in generative ai is **LLM**.

**What is LLM ?**

LLM stand for large language model. LLM basically predict the next word. If i provide the input query as **hello** to gpt model, based on the data it was trained, it will predict and returns
