Creating Your First Agent

import autogen

# Language model configuration
config_list = [
    {
        "model": "gpt-4",
        "api_key": "YOUR_API_KEY"
    }
]
# Create assistant agent
assistant = autogen.AssistantAgent(
    name="assistant",
    llm_config={"config_list": config_list}
)
# Create user proxy agent
user_proxy = autogen.UserProxyAgent(
    name="user_proxy",
    code_execution_config={"work_dir": "coding"}
