We provide the following free resources for registered Dify cloud users (sign up at dify.ai):

• 600,000 free Claude model tokens to build Claude-powered apps
• 200 free OpenAI queries to build OpenAI-based apps

2. Visual orchestration: Build an AI app in minutes by writing and debugging prompts visually.

3. Text embedding: Fully automated text preprocessing embeds your data as context without complex concepts. Supports PDF, TXT, and syncing data from Notion, webpages, APIs.

4. API-based: Backend-as-a-service. Access web apps directly or integrate via APIs without complex backend setup.

5. Plugins: Dify "Smart Chat" now supports first-party plugins like web browsing, Google search, Wikipedia to enable online lookup, analyzing web content, and explaining the AI's reasoning process conversationally.

6. Team workspaces: Team members can join workspaces to collaboratively edit, manage, and use team AI apps.

7. Data labeling and improvement: Visually inspect AI app logs and improve data via labeling. Observe the AI's reasoning process to continuously enhance performance. (Coming soon)

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 file. Before running the installation command, make sure that Docker and Docker Compose are installed on your machine:

cd docker
docker compose up -d

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

Helm Chart

A big thanks to @BorisPolonsky for providing us with a Helm Chart 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 file and manually set the environment configuration. After making the changes, please run 'docker-compose up -d' again.

Roadmap

Features under development:

• Datasets, supporting more datasets, e.g. syncing content from Notion or webpages We will support more datasets, including text, webpages, and even Notion content. Users can build AI applications based on their own data sources.
• Plugins, introducing ChatGPT Plugin-standard plugins for applications, or using Dify-produced plugins We will release plugins complying with ChatGPT standard, or Dify's own plugins to enable more capabilities in applications.

Q&A

Q: What can I do with Dify?

A: Dify is a simple yet powerful LLM development and operations tool. You can use it to build commercial-grade applications, personal assistants. If you want to develop your own applications, LangDifyGenius can save you backend work in integrating with OpenAI and offer visual operations capabilities, allowing you to continuously improve and train your GPT model.

Q: How do I use Dify to "train" my own model?

A: A valuable application consists of Prompt Engineering, context enhancement, and Fine-tuning. We've created a hybrid programming approach combining Prompts with programming languages (similar to a template engine), making it easy to accomplish long-text embedding or capturing subtitles from a user-input Youtube video - all of which will be submitted as context for LLMs to process. We place great emphasis on application operability, with data generated by users during App usage available for analysis, annotation, and continuous training. Without the right tools, these steps can be time-consuming.

Q: What do I need to prepare if I want to create my own application?

A: We assume you already have an OpenAI API Key; if not, please register for one. If you already have some content that can serve as training context, that's great!

Q: What interface languages are available?

A: English and Chinese are currently supported, and you can contribute language packs to us.
