# Understanding ollama API

## Introduction

We have studied about how ollama can run the [Large Language models](https://www.mindstick.com/news/3347/microsoft-releases-bing-chat-enterprise-and-microsoft-365-copilot-pricing-information) (LLMs) locally in your computer system. but in real world application user not only communicate with terminal. \
suppose you have to make some application like:

- AI chatbot
- Resume Analyzer
- News classifier
- Personal [AI](https://www.mindstick.com/services/artificial-intelligence) Assistant

Then how your Application will communicate with ollama is defined by ollama API.

## what is an API?

API stands for Application [Programming](https://www.mindstick.com/articles/12214/web-development-company-in-india-laid-on-the-foundation-of-concrete-java-programming) Interface. API acts as bridge between two software which helps then to communicate with each other.

*example:-*

```plaintext
Your Application → API → AI Model
```

## Why does ollama provide an API?

The problem which have to faced by the user if no API exist is that to communicate with the model we have to use terminal every time. If you are creating any Website or Application then user will not communicate with the terminal so to resolve this problem ollama provides API services.

*example:-*

```plaintext
User → website → ollama API → llama 3 → response
```

so ollama provides API.

## How does ollama API works?

when any user enters any prompt like *“what is* [*Artificial Intelligence*](https://www.mindstick.com/services/artificial-intelligence)*?”* then application do not communicate directly with model.

```plaintext
User → Application → ollama API → llama 3 → generated response → application → user
```

API handles the [communication](https://www.mindstick.com/articles/126321/5-fails-and-fixes-of-the-office-communication) between the user and the model.

## ollama API server

when ollama is installed it provides a local server who's default address is:

```plaintext
http://localhost:11434
where, localhost = current computer
             11434 = port number
```

means ollama's API run in your system.

**[Understanding](https://www.mindstick.com/news/2555/understanding-the-work-of-bionutrients-everything-you-need-to-know) localhost**

Sometimes Beginners get confused by the localhost. localhost is your own computer. when you enter in browser:

```plaintext
http://localhost:11434
```

then this request not use internet it works in your local system.

## Why is ollama API Important?

Without API you can only use terminal for any interaction with the model. But with API you can make multiple applications like [Web Applications](https://www.mindstick.com/blog/11464/improve-your-understanding-of-web-applications), Desktop application, chatbots, AI assistants, [mobile apps](https://www.mindstick.com/articles/12316/plan-your-next-holidays-with-these-popular-mobile-apps), etc.
