aion-adk

aion-adk is the existing Google ADK helper package for Aion-backed model configuration. It contains the aion_lite_llm helper used by ADK agents that should call Aion’s model service. MCP toolset bindings live in the separate aion-authoring-adk package. Plugin symbols live in the separate aion-plugin-adk package. Use concrete submodule imports. The shared aion.adk package is a namespace for ADK-related packages and does not re-export model, plugin, or MCP helpers at the top level.

Install

pip install aion-adk

When installing through the umbrella SDK package, use:

pip install "aion-sdk[adk-authoring]"

Model helper

Use aion_lite_llm when Google ADK model calls should flow through Aion’s model service.

from google.adk.agents import Agent

from aion.adk.models import aion_lite_llm

agent = Agent(
    name="research_agent",
    model=aion_lite_llm("model-id-from-control-plane"),
)

The helper configures ADK’s LiteLlm with the Aion model-service base URL and a JWT provider backed by the configured AION_CLIENT_ID and AION_CLIENT_SECRET.
