Langchain, OpenAI and Streamlit - Using Langchain & Streamlit to Build a Recipe Generator

Blog Post: https://bugbytes.io/posts/langchain-s...

In this video, we'll build a recipe generator app which allows users to enter a list of ingredients, and we use langchain to send requests to OpenAI to generate potential recipes based on that list of ingredients.

We will use Streamlit to build a small UI to enable users to enter ingredients, and then display the recipes returned by the language model.

We will see a few features of langchain in doing so, including PromptTemplate, LLMChain, and SequentialChain / SimpleSequentialChain objects
