ADK — Connecting to Other LLMs

ADK — Connecting to Other LLMs

ADK is optimized for Gemini, but you can connect to any model via:

• LiteLLM — a package that handles requests across providers.
• OpenRouter — gives you access to any LLM. You pay for credits through OpenRouter, and it provides one API key to access all models.
  • Put the API key in the .env file.
  • Rankings: https://openrouter.ai/rankings

Example

import os
from google.adk.models.lite_llm import LiteLlm
 
model = LiteLlm(
    model="openrouter/openai/gpt-4.1",
    api_key=os.getenv("OPENROUTER_API_KEY"),
)
