VideoSDK AI Agents: The Revolutionary Open-Source Framework That's Transforming Real-Time Multimodal Conversational AI with 588+ GitHub Stars

In the rapidly evolving landscape of conversational AI, a groundbreaking framework has emerged that's revolutionizing how developers build real-time multimodal AI agents. VideoSDK AI Agents, with its impressive 588+ GitHub stars and growing community of 82 forks, represents a paradigm shift in creating intelligent, voice-enabled agents that can seamlessly interact with users through natural conversation.

🚀 What Makes VideoSDK AI Agents Revolutionary?

VideoSDK AI Agents is an open-source Python framework built on top of the VideoSDK Python SDK that enables AI-powered agents to join VideoSDK rooms as participants. This innovative approach creates a real-time bridge between AI models (like OpenAI, Gemini, or AWS Nova) and users, facilitating seamless voice and media interactions.

Key Revolutionary Features:

• 🎤 Real-time Communication: Agents can listen, speak, and interact live in meetings with ultra-low latency
• 📞 SIP & Telephony Integration: Seamlessly connect agents to phone systems via SIP for call handling and PSTN access
• 🧍 Virtual Avatars: Add lifelike avatars using Simli integration for enhanced user interaction
• 🤖 Multi-Model Support: Integrate with OpenAI, Gemini, AWS NovaSonic, Azure, and 30+ other providers
• 🧩 Cascading Pipeline: Seamlessly integrate different providers for STT, LLM, and TTS
• ⚡ Realtime Pipeline: Use unified realtime models for lowest possible latency
• 🧠 Conversational Flow: Advanced turn detection and VAD for smooth interactions
• 🛠️ Function Tools: Extend agent capabilities with custom functions and external APIs
• 🌐 MCP Integration: Connect agents to external data sources using Model Context Protocol
• 🔗 A2A Protocol: Enable agent-to-agent interactions for complex workflows
• 📊 Observability: Built-in OpenTelemetry tracing and metrics collection
• 🚀 CLI Tool: Run and test agents locally with the videosdk CLI

🏗️ Architecture Overview

The VideoSDK AI Agents framework connects four critical components:

1. Your Infrastructure: Where your agent logic and business rules reside
2. Agent Worker: The processing engine that handles AI model interactions
3. VideoSDK Room: The real-time communication layer
4. User Devices: Client applications where users interact with agents

This architecture enables natural voice and multimodal interactions between users and intelligent agents in real-time, making it perfect for applications like customer service, virtual assistants, educational tools, and more.

🛠️ Getting Started: Building Your First AI Agent

Prerequisites

Before diving in, ensure you have:

• Python 3.12 or higher
• A VideoSDK authentication token from app.videosdk.live
• API keys for your chosen AI services (OpenAI, Google, etc.)

Installation

Create and activate a virtual environment:

# macOS / Linux

venv\Scripts\activate

Install the core framework:

pip install videosdk-agents

Install optional plugins based on your needs:

# Example: Install turn detector plugin
pip install videosdk-plugins-turn-detector

# Install with specific plugins
pip install videosdk-agents[openai,elevenlabs,silero]

Creating Your First Voice Agent

Here's how to create a custom voice agent:

from videosdk.agents import Agent, function_tool
import aiohttp

# External Function Tool
@function_tool
async def get_weather(latitude: str, longitude: str):
    """Get weather information for given coordinates"""
    url = f"https://api.open-meteo.com/v1/forecast?latitude={latitude}&longitude={longitude}¤t=temperature_2m"
    async with aiohttp.ClientSession() as session:
        async with session.get(url) as response:
            if response.status == 200:
                data = await response.json()
                return {
                    "temperature": data["current"]["temperature_2m"],
                    "temperature_unit": "Celsius",
                }
            else:
                raise Exception(f"Failed to get weather data: {response.status}")

class VoiceAgent(Agent):
    def __init__(self):
        super().__init__(
            instructions="You are a helpful voice assistant that can answer questions and help with tasks.",
            tools=[get_weather]  # Register external tools
        )

    async def on_enter(self) -> None:
        """Called when the agent first joins the meeting"""
        await self.session.say("Hi there! How can I help you today?")

    async def on_exit(self) -> None:
        """Called when the agent exits the meeting"""
        await self.session.say("Goodbye!")

    # Internal Function Tool
    @function_tool
    async def get_horoscope(self, sign: str) -> dict:
        """Get horoscope for a zodiac sign"""
        horoscopes = {
            "Aries": "Today is your lucky day!",
            "Taurus": "Focus on your goals today.",
            "Gemini": "Communication will be important today.",
        }
        return {
            "sign": sign,
            "horoscope": horoscopes.get(sign, "The stars are aligned for you today!"),
        }

Setting Up the Pipeline

Configure your AI pipeline using Google's Gemini for real-time processing:

from videosdk.plugins.google import GeminiRealtime, GeminiLiveConfig
from videosdk.agents import RealTimePipeline, JobContext

async def start_session(context: JobContext):
    # Initialize the AI model
    model = GeminiRealtime(
        model="gemini-2.5-flash-native-audio-preview-12-2025",
        api_key="YOUR_GOOGLE_API_KEY",  # Or set GOOGLE_API_KEY in .env
        config=GeminiLiveConfig(
            voice="Leda",  # Available: Puck, Charon, Kore, Fenrir, Aoede, Leda, Orus, Zephyr
            response_modalities=["AUDIO"]
        )
    )

    pipeline = RealTimePipeline(model=model)
    # Continue to session setup...

Complete Agent Session Setup

import asyncio
from videosdk.agents import AgentSession, WorkerJob, RoomOptions, JobContext

async def start_session(context: JobContext):
    # ... previous setup code ...

    # Create the agent session
    session = AgentSession(
        agent=VoiceAgent(),
        pipeline=pipeline
    )

    try:
        await context.connect()
        # Start the session
        await session.start()
        # Keep the session running
        await asyncio.Event().wait()
    finally:
        # Clean up resources
        await session.close()
        await context.shutdown()

def make_context() -> JobContext:
    room_options = RoomOptions(
        room_id="YOUR_MEETING_ID",  # Replace with actual meeting ID
        auth_token="YOUR_VIDEOSDK_AUTH_TOKEN",  # Or set in .env
        name="AI Assistant",
        playground=True,
        vision=True  # Available with Google Gemini Live API
    )

    return JobContext(room_options=room_options)

if __name__ == "__main__":
    job = WorkerJob(entrypoint=start_session, jobctx=make_context)
    job.start()
