| **2. Comprehensive model support**: | |
| Seamless integration with hundreds of proprietary / open-source LLMs from dozens of inference providers and self-hosted solutions, covering GPT, Mistral, Llama3, and any OpenAI API-compatible models. A full list of supported model providers can be found [here](https://docs.dify.ai/getting-started/readme/model-providers). | |
|  | |
| **3. Prompt IDE**: | |
| Intuitive interface for crafting prompts, comparing model performance, and adding additional features such as text-to-speech to a chat-based app. | |
| **4. RAG Pipeline**: | |
| Extensive RAG capabilities that cover everything from document ingestion to retrieval, with out-of-box support for text extraction from PDFs, PPTs, and other common document formats. | |
| **5. Agent capabilities**: | |

| ## Using Dify | |
| - **Cloud </br>** | |
| We host a [Dify Cloud](https://dify.ai) service for anyone to try with zero setup. It provides all the capabilities of the self-deployed version, and includes 200 free GPT-4 calls in the sandbox plan. | |
| - **Self-hosting Dify Community Edition</br>** | |
| Quickly get Dify running in your environment with this [starter guide](#quick-start). | |
| Use our [documentation](https://docs.dify.ai) for further references and more in-depth instructions. | |
| - **Dify for enterprise / organizations</br>** | |
| We provide additional enterprise-centric features. [Schedule a meeting with us](https://cal.com/guchenhe/30min) or [send us an email](mailto:[email protected]?subject=[GitHub]Business%20License%20Inquiry) to discuss enterprise needs. </br> | |
| > For startups and small businesses using AWS, check out [Dify Premium on AWS Marketplace](https://aws.amazon.com/marketplace/pp/prodview-t22mebxzwjhu6) and deploy it to your own AWS VPC with one-click. It's an affordable AMI offering with the option to create apps with custom logo and branding. | |
| ## Staying ahead | |
| Star Dify on GitHub and be instantly notified of new releases. | |
|  | |
| ## Quick start | |
| > Before installing Dify, make sure your machine meets the following minimum system requirements: | |
| > | |
| >- CPU >= 2 Core | |
| >- RAM >= 4GB | |
| </br> | |
| 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 process. | |
| > If you'd like to contribute to Dify or do additional development, refer to our [guide to deploying from source code](https://docs.dify.ai/getting-started/install-self-hosted/local-source-code) | |
| ## Next steps | |
| 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 [here](https://docs.dify.ai/getting-started/install-self-hosted/environments). | |
| If you'd like to configure a highly-available setup, there are community-contributed [Helm Charts](https://helm.sh/) which allow Dify to be deployed on Kubernetes. | |
| - [Helm Chart by @LeoQuote](https://github.com/douban/charts/tree/master/charts/dify) | |
