# 🦜️🔗 LangChain-mini This is a very simple re-implementation of [LangChain](https://github.com/hwchase17/langchain), in ~100 lines of code. In essence, it is an LLM (GPT-3.5) powered chat application that is able to use tools (Google search and a calculator) in order to hold conversations and answer questions. Here's an example: ~~~ Q: What is the world record for solving a rubiks cube? The world record for solving a Rubik's Cube is 4.69 seconds, held by Yiheng Wang (China). Q: Can a robot solve it faster? The fastest time a robot has solved a Rubik's Cube is 0.637 seconds. Q: Who made this robot? Infineon created the robot that solved a Rubik's Cube in 0.637 seconds. Q: What time would an average human expect for solving? It takes the average person about three hours to solve a Rubik's cube for the first time. ~~~ This is not intended to be a replacement for LangChain, instead it was built for fun and educational purposes. If you're interested in how LangChain, and similar tools work, this is a good starting point. For more information about this project, read the accompanying blogpost - [Re-implementing LangChain in 100 lines of code](https://blog.scottlogic.com/2023/05/04/langchain-mini.html) ## Running / developing Install dependencies, and run (with node >= v18): ~~~ % npm install ~~~ You'll need to have both an OpenAI and SerpApi keys. These can be supplied to the application via a `.env` file: ~~~ OPENAI_API_KEY="..." SERPAPI_API_KEY="..." ~~~ You can now run the chain: ~~~ % node index.mjs How can I help? what was the name of the first man on the moon? Neil Armstrong ~~~
