📄️ Async API

LangChain provides async support by leveraging the asyncio library.

All classes inherited from Chain offer a few ways of running chain logic. The most direct one is by using call:

To implement your own custom chain you can subclass Chain and implement the following methods:

Chains can be initialized with a Memory object, which will persist data across calls to the chain. This makes a Chain stateful.

This walkthrough demonstrates how to incorporate OpenAI function-calling API's in a chain. We'll go over:
