Setup

1Create an OpenAIChatCompletionClient with base_url = https://api.ultragpt.pro/v1. Models outside OpenAI's list need model_info.

# pip install autogen-agentchat "autogen-ext[openai]"
import os
from autogen_agentchat.agents import AssistantAgent
from autogen_ext.models.openai import OpenAIChatCompletionClient

client = OpenAIChatCompletionClient(
    model="grok-4.7",
    base_url="https://api.ultragpt.pro/v1",
    api_key=os.environ["ULTRAGPT_API_KEY"],
    model_info={"vision": False, "function_calling": True, "json_output": True, "family": "unknown", "structured_output": True},
)
agent = AssistantAgent("assistant", model_client=client)

Tips

Any model id from Models works; suffixes like :online (web search) and :nitro work too.
Give each tool its own key with a spend limit, so usage shows separately in Activity.
