AG2 (formerly AutoGen) is a framework for building multi-agent conversational AI systems. AgentOps provides seamless, automatic instrumentation for AG2 — just call agentops.init() and all agent interactions are tracked.

​
Installation

pip install agentops pyautogen

​
Setting Up API Keys

Before using AG2 with AgentOps, you need to set up your API keys. You can obtain: Then to set them up, you can either export them as environment variables or set them in a .env file. 
export OPENAI_API_KEY="your_openai_api_key_here"
export AGENTOPS_API_KEY="your_agentops_api_key_here"
Then load the environment variables in your Python code: 
from dotenv import load_dotenv
import os

# Load environment variables from .env file
load_dotenv()

# Set up environment variables with fallback values
os.environ["OPENAI_API_KEY"] = os.getenv("OPENAI_API_KEY")
os.environ["AGENTOPS_API_KEY"] = os.getenv("AGENTOPS_API_KEY")

​
Usage

Initialize AgentOps at the beginning of your application to automatically track all AG2 agent interactions: 
import agentops
import autogen
import os

# Initialize AgentOps
agentops.init()

# Configure your AG2 agents
config_list = [
    {
        "model": "gpt-4",
        "api_key": os.getenv("OPENAI_API_KEY"),
    }
]

llm_config = {
    "config_list": config_list,
    "timeout": 60,
}

# Create a single agent
assistant = autogen.AssistantAgent(
    name="assistant",
    llm_config=llm_config,
    system_message="You are a helpful AI assistant."
)

user_proxy = autogen.UserProxyAgent(
    name="user_proxy",
    human_input_mode="TERMINATE",
    max_consecutive_auto_reply=10,
    is_termination_msg=lambda x: x.get("content", "").rstrip().endswith("TERMINATE"),
    code_execution_config={"last_n_messages": 3, "work_dir": "coding"},
)

# Initiate a conversation
user_proxy.initiate_chat(
    assistant,
    message="How can I implement a basic web scraper in Python?"
)
