conversation_app.py

Overview

conversation_app.py is a Flask-based RESTful API module that manages conversations and dialogs within the InfiniFlow platform. It provides endpoints for creating, updating, retrieving, deleting, and interacting with conversations and dialogs powered by LLM (Large Language Model) services. The file integrates with various service layers to handle user authentication, conversation persistence, dialog management, LLM-based chat completions, text-to-speech synthesis, and knowledge base queries.

Key functionalities include:

This module depends heavily on services like ConversationService, DialogService, TenantLLMService, and others to abstract database interactions and LLM operations.
