[Google ADK](https://github.com/google/adk-python) is an open-source, code-first Python framework for building, evaluating, and deploying sophisticated AI agents. While optimized for Gemini, ADK is model-agnostic and supports LiteLLM for using 100+ providers.

```python
from google.adk.agents.llm_agent import Agent
from google.adk.models.lite_llm import LiteLlm

root_agent = Agent(
    model=LiteLlm(model="openai/gpt-5.6-terra"),  # Or any LiteLLM-supported model
    name="my_agent",
    description="An agent using LiteLLM",
    instruction="You are a helpful assistant.",
    tools=[your_tools],
)
```
