AutoGen / AG2

Community / legacy integration. AutoGen is officially in maintenance mode upstream — Microsoft has named its Agent Framework as the planned successor. This adapter is a thin alias for the generic OpenTelemetry integration — it keeps working, but it isn’t part of the first-class tier (LangChain/LangGraph, OpenAI Agents SDK, the Claude ecosystem). For new projects, prefer one of those or the generic OTel path; when Microsoft’s Agent Framework stabilizes, its OTel spans will flow through the same generic path.

The AutoGen integration works with both classic AutoGen and AG2 (the community fork). Like CrewAI, it routes through OpenTelemetry.

Install

pip install decimalai

Install AutoGen separately if you don’t already have it.

Use

import os
import decimalai
decimalai.init(api_key="dai_sk_...", autogen=True)

from autogen import AssistantAgent, UserProxyAgent

assistant = AssistantAgent(
    "assistant",
    llm_config={"config_list": [{"model": "gpt-4o", "api_key": os.environ["OPENAI_API_KEY"]}]},
)
user_proxy = UserProxyAgent(
    "user_proxy",
    human_input_mode="NEVER",
    code_execution_config=False,
)

# Agent conversations and tool usage are traced
chat_result = user_proxy.initiate_chat(assistant, message="Hello")

What gets captured

Each turn of the agent conversation
Tool invocations and their results
LLM calls behind each agent’s reasoning
Group chat coordination spans

Caveats

AutoGen’s conversation model is turn-based, not tree-based. DecimalAI flattens turns into a sequential trace; if you want a tree view, use the explicit @decimalai.trace decorator on your top-level orchestrator function.
Manifest detection captures tool names only.
