The hype around large language models (LLMs) is continuing to grow, with more and more companies releasing tools to make people's life easier. So what exactly are these tools that are helping build the world of LLMs? Well, one of them is Flowise AI


What is Flowise AI?


Flowise AI is an open-source UI visual tool used to help develop LangChain apps. Before we get into more about Flowise AI, let’s quickly define LangChain. LangChain is a framework/python library that helps you make use of LLMs to build your own custom NLP applications.

Flowise uses LangChain as its agent executor, Chroma as its vector store, OpenAI for embeddings, HuggingFace’s inference model, GitHub as a document loader, and SERP for query API. Its Graphic User Interface is very helpful in constructing LLM-based apps built on LangChain.js. 

So what makes it so easy and helpful? The drag-and-drop tool. Everybody loves a drag-and-drop, especially when you are customizing your NLP application. The even bigger plus is that it does not require any coding experience!
