Deploy Any Agent in 60 Seconds

Intelligent, composable agents that collaborate through shared context.

pip install ag2[openai]

from autogen import ConversableAgent, LLMConfig

coding_agent = ConversableAgent("coding_agent", llm_config=LLMConfig(config_list={"model": "gpt-5-nano"}))

response = coding_agent.run(message="Write a Python function to calculate fibonacci and when you're done say 'TERMINATE'.")

response.process()
