## Introduction: What is Dify

Dify is an open-source Large Language Model (LLM) application development platform, whose name is derived from the acronym **D**o **I**t **F**or **Y**ou. The platform combines Backend-as-a-Service (BaaS) with LLMOps concepts, aiming to help developers quickly build, deploy, and manage generative AI applications. Both technical developers and non-technical innovators can quickly turn AI prototypes into production-grade applications through Dify's visual interface.

## Panoramic View of Core Features

Dify provides a complete feature matrix covering the entire lifecycle from prototype design to production deployment:

## 1. Visual Workflow Orchestration

The core highlight of Dify lies in its intuitive visual canvas, where users can build and test complex AI workflows on a graphical interface. This WYSIWYG (What You See Is What You Get) orchestration method significantly lowers the development threshold for multi-step AI processes, supporting advanced control structures such as conditional branching, loops, and parallel processing.

## 2. Comprehensive Model Support

The platform seamlessly integrates hundreds of proprietary and open-source large language models, covering the following major providers:
- OpenAI (GPT series)
- Anthropic (Claude series)
- Open-source models (Llama3, Mistral, etc.)
- Self-hosted solutions
- Any model compatible with the OpenAI API format

This flexibility allows developers to freely choose the underlying model based on cost, performance, and privacy requirements.

## 3. Intelligent Prompt Engineering IDE

Dify has a built-in dedicated Prompt IDE, providing an intuitive interface for:
- Carefully designing and debugging prompts
- Comparing output effects of different models
- Adding enhanced features like text-to-speech to chat applications
- Version management and A/B testing

## 4. Enterprise-Grade RAG Pipeline

Retrieval-Augmented Generation (RAG) is another core capability of Dify. The platform provides complete RAG capabilities from document ingestion to retrieval, supporting out-of-the-box:
- Text extraction from common document formats like PDF, PPT, Word
- Automatic chunking and vectorization processing
- Hybrid strategy of semantic retrieval and keyword retrieval
- Citation tracing and answer confidence evaluation
