Is your feature request related to a problem? Please describe.
Currently, it is not possible to set the url for model requests separately

root_agent = (Agent(
 name="weather_agent_v1",
 model="gemini-3-pro-preview",
 base_url="https://sg.uiuiapi.com/v1/chat/completions",
 description="Provides weather information for specific cities.",
 instruction="You are a helpful weather assistant. "
 "When the user asks for the weather in a specific city, "
 "use the 'get_weather' tool to find the information. "
 "If the tool returns an error, inform the user politely. "
 "If the tool is successful, present the weather report clearly.",
 tools=[get_weather,google_search], # Pass the function directly
))

Describe the solution you'd like
ADK should be an open framework, hoping to support the configuration of third-party urls and keys like langchain
Describe alternatives you've considered

I don't know if I understand your request completely, but if you want to use other models (not from Google) you can already do that using LiteLlm: https://docs.litellm.ai/docs/tutorials/google_adk

What were the considerations behind this design? When using Langchain, I can configure it directly without the need for other third-party libraries. Although Langchain requires defining the URL of the LLM each time, it is quite flexible. And ADK surprised me a lot.

@WDEP-good Thanks for the update. The request is currently being reviewed, and I will let you know if anything further is needed. Thank you for your understanding.

For Gemini models, you can customize it's URL with the base_url attribute on the Gemini class.
For other models, you can either use LiteLLM, or our new OpenAI model support in labs: https://github.com/google/adk-python/tree/main/src/google/adk/labs/openai
We will need to add the base_url support in OpenAI model too so you can point it at any backends that support OpenAI specs.

for an openai-compatible endpoint, use LiteLlm with model openai/ and api_base set to your host. a first-class base_url on the openai model is still open work, so closing this as answered.
