Dify.AI

English | 简体中文 | 日本語 | Español | Klingon

Dify is an LLM application development platform that has already seen over 100,000 applications built on Dify.AI. It integrates the concepts of Backend as a Service and LLMOps, covering the core tech stack required for building generative AI-native applications, including a built-in RAG engine. With Dify, you can self-deploy capabilities similar to Assistants API and GPTs based on any LLMs.

Use Cloud Services

Using Dify.AI Cloud provides all the capabilities of the open-source version, and includes a complimentary 200 GPT trial credits.

Why Dify

Dify features model neutrality and is a complete, engineered tech stack compared to hardcoded development libraries like LangChain. Unlike OpenAI's Assistants API, Dify allows for full local deployment of services.

Features

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. Agents: A Function Calling based Agent framework that allows users to configure what they see is what they get. Dify includes basic plugin capabilities like Google Search.

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