FAQ

Do I need to know how to code? No. Dify’s visual builder lets you create AI applications by dragging and dropping components. For advanced customizations, a code editor is available but entirely optional.

What AI models does Dify support? Dify works with OpenAI (GPT-4, GPT-4o), Anthropic (Claude), Google (Gemini), local models via Ollama, and dozens more. You need your own API key for cloud models; local models work with Ollama for free.

Is Dify really free? Yes. The self-hosted version available here is completely free with no feature limitations. Dify also offers a cloud version with a generous free tier.

How is Dify different from ChatGPT? ChatGPT is a single chat interface. Dify lets you build customized AI applications with specific knowledge, behavior, and tools — deployable as standalone web apps for teams or customers.
