VideoSDK AI Agents: Build Real-time Multimodal Conversational AI

Introduction

VideoSDK AI Agents is an open-source Python framework designed for developing real-time, multimodal conversational AI agents. It provides a robust infrastructure to connect your agent worker, VideoSDK room, and user devices, enabling natural voice and media interactions between users and intelligent agents. This framework is built on top of the VideoSDK Python SDK, allowing AI-powered agents to seamlessly join VideoSDK rooms as participants.

Key features include:

Real-time Communication (Audio/Video): Agents can listen, speak, and interact live in meetings.
SIP & Telephony Integration: Connect agents to phone systems via SIP for call handling and routing.
Virtual Avatars: Enhance interaction and presence with lifelike avatars using Simli.
Multi-Model Support: Integrate with leading AI models like OpenAI, Gemini, AWS NovaSonic, and more.
Cascading and Realtime Pipelines: Flexible pipeline options for STT, LLM, and TTS.
Function Tools: Extend agent capabilities with custom functions for event scheduling, data retrieval, and more.
Observability: Built-in OpenTelemetry tracing and metrics collection.
CLI Tool: Run and test agents locally with the videosdk CLI.

Installation

To get started with VideoSDK AI Agents, follow these steps:

Prerequisites

Before you begin, ensure you have:

A VideoSDK authentication token (generate from app.videosdk.live)
A VideoSDK meeting ID (generate using the Create Room API or dashboard)
Python 3.12 or higher
Third-Party API Keys for services like OpenAI, ElevenLabs, Google Gemini, etc.

Steps

Create and activate a virtual environment with Python 3.12 or higher.
```
python3 -m venv venv
source venv/bin/activate
```
(For Windows, use python -m venv venv and venv\Scripts\activate)
Install the core VideoSDK AI Agent package:
```
pip install videosdk-agents
```
Install Optional Plugins: Plugins integrate different providers for Realtime, STT, LLM, TTS, VAD, Avatar, and SIP. Install what your use case needs.
```
# Example: Install the Turn Detector plugin
pip install videosdk-plugins-turn-detector
```
You can also install with specific plugins:
```
pip install videosdk-agents[openai,elevenlabs,silero]
```

Examples

The framework offers various examples to demonstrate its capabilities and common use cases:

AI Telephony Agent Quickstart: A hospital appointment booking agent via voice. View Example
AI Whatsapp Agent Quickstart: An agent for asking about available hotel rooms and booking on the go. View Example
Multi Agent System: A customer care agent that transfers loan-related queries to a Loan Specialist Agent. View Example
Agent with Knowledge (RAG): An agent that answers questions based on documentation knowledge. View Example
Virtual Avatar Agent: A virtual avatar agent that presents weather forecasts. View Example
