This repository is used to save my extensions for the Dify project.
chat-dify is a demo created using the assistant-ui project, demonstrating how to call the Dify Chat API like calling LLM APIs.
The project first implements a Dify Provider of the Vercel AI SDK, located in the chat-dify/lib/chat/providers/dify directory, allowing developers to use the Vercel AI SDK to call the Dify API like calling an LLM. It then implements the chat UI based on assistant-ui.

Text similarity calculation, used to measure the similarity between the content recalled from the knowledge base and the answers provided by the LLM. For example, if you recall 3 pieces of material from the knowledge base and provide them to the LLM to answer a user's question, you may want to know which piece of material the LLM's answer referenced, or if it referenced any of the provided materials at all. This can be determined by calculating the similarity between them.
