# The goal of this file is to provide a FastAPI application for handling
# chat requests amd generation AI-powered responses using conversation chains.
# The application uses the LangChaing library, which includes a chatOpenAI model
# for natural language processing.

# The `StreamingConversationChain` class is responsible for creating and storing
# conversation memories and generating responses. It utilizes the `ChatOpenAI` model
# and a callback handler to stream responses as they're generated.

# The application defines a `ChatRequest` model for handling chat requests,
