An implementation of a food ordering bot with langchain and chatgpt. I've also made a version for Anthropic Claude LLM.
For chatgpt version, export OPENAI_API_KEY, and edit data.py. Run with python start.py.
For claude version, export ANTHROPIC_API_KEY, and edit data.py. Run with python start.py.
This code enables question answering on custom data using a list of dictionaries, which can also handle larger files and databases. It also facilitates the execution of custom tools, such as tracking internal states (e.g., cart), performing calculations (e.g., total), and calling external APIs (e.g., submitting an order), all while keeping track of the dialog context.
