    "# Auto Generated Agent Chat: Function Inception\n",
    "\n",
    "AG2 offers conversable agents powered by LLM, tool or human, which can be used to perform tasks collectively via automated chat. This framework allows tool use and human participation through multi-agent conversation. Please find documentation about this feature [here](https://docs.ag2.ai/docs/Use-Cases/agent_chat).\n",
    "\n",
    "In this notebook, we demonstrate how to use `AssistantAgent` and `UserProxyAgent` to give them the ability to auto-extend the list of functions the model may call. Functions need to be registered to `UserProxyAgent`, which will be responsible for executing any function calls made by `AssistantAgent`. The assistant also needs to know the signature of functions that may be called. A special `define_function` function is registered, which registers a new function in `UserProxyAgent` and updates the configuration of the assistant.\n",
    "\n",
    "In the example scenario, the user first asks to define a function that gets a URL and prints the response body. Then the user asks to print the response body, and the assistant suggests to the user to call the new function.\n",
    "\n",
    "## Requirements\n",
    "\n",
    "AG2 requires `Python>=3.9`."
