   Dify.AI Unveils AI Agent: Creating GPTs and Assistants with Various LLMs
  </a>
</p>

**Dify** is an LLM application development platform that has helped built over **100,000** applications. It integrates BaaS and LLMOps, covering the essential tech stack for building generative AI-native applications, including a built-in RAG engine. Dify allows you to **deploy your own version of Assistants API and GPTs, based on any LLMs.**

## Using our Cloud Services

You can try out [Dify.AI Cloud](https://dify.ai) now. It provides all the capabilities of the self-deployed version, and includes 200 free requests to OpenAI GPT-3.5.

## Dify vs. LangChain vs. Assistants API

| Feature | Dify.AI | Assistants API | LangChain |
|---------|---------|----------------|-----------|
| **Programming Approach** | API-oriented | API-oriented | Python Code-oriented |
| **Ecosystem Strategy** | Open Source | Close Source | Open Source |
| **RAG Engine** | Supported | Supported | Not Supported |
| **Prompt IDE** | Included | Included | None |
| **Supported LLMs** | Rich Variety | OpenAI-only | Rich Variety |
| **Local Deployment** | Supported | Not Supported | Not Applicable |



## Features

![](./images/models.png)

**1. LLM Support**: Integration with OpenAI's GPT family of models, or the open-source Llama2 family models. In fact, Dify supports mainstream commercial models and open-source models (locally deployed or based on MaaS).

**2. Prompt IDE**: Visual orchestration of applications and services based on LLMs with your team.

**3. RAG Engine**: Includes various RAG capabilities based on full-text indexing or vector database embeddings, allowing direct upload of PDFs, TXTs, and other text formats.

**4. AI Agent**: Based on Function Calling and ReAct, the Agent inference framework allows users to customize tools, what you see is what you get. Dify provides more than a dozen built-in tool calling capabilities, such as Google Search, DELL·E, Stable Diffusion, WolframAlpha, etc.


**5. Continuous Operations**: Monitor and analyze application logs and performance, continuously improving Prompts, datasets, or models using production data.

## Install the Community Edition

### System Requirements

Before installing Dify, make sure your machine meets the following minimum system requirements:

- CPU >= 2 Core
- RAM >= 4GB

### Quick Start

The easiest way to start the Dify server is to run our [docker-compose.yml](docker/docker-compose.yaml) file. Before running the installation command, make sure that [Docker](https://docs.docker.com/get-docker/) and [Docker Compose](https://docs.docker.com/compose/install/) are installed on your machine:

```bash
cd docker
docker compose up -d
```

After running, you can access the Dify dashboard in your browser at [http://localhost/install](http://localhost/install) and start the initialization installation process.

### Helm Chart

Big thanks to @BorisPolonsky for providing us with a [Helm Chart](https://helm.sh/) version, which allows Dify to be deployed on Kubernetes.
You can go to https://github.com/BorisPolonsky/dify-helm for deployment information.

### Configuration

If you need to customize the configuration, please refer to the comments in our [docker-compose.yml](docker/docker-compose.yaml) file and manually set the environment configuration. After making the changes, please run `docker-compose up -d` again. You can see the full list of environment variables in our [docs](https://docs.dify.ai/getting-started/install-self-hosted/environments).
