Google ADK
Google's Agent Development Kit (ADK) supports custom OpenAI-compatible endpoints via its LiteLLM integration.
Install
pip install google-adk litellmConfigure
from google.adk.agents import Agent
from google.adk.models.lite_llm import LiteLlm
agent = Agent(
model=LiteLlm(
model="openai/{{selectedModel.id}}",
api_base="https://api.doubleword.ai/v1",
api_key="{{apiKey}}",
),
name="my_agent",
instruction="You are a helpful assistant.",
)The openai/ prefix tells LiteLLM to use the OpenAI-compatible code path. The part after the slash should match a model name configured in your Control Layer.
