How do I change/set the model in Agents SDK for model_settings.DEFAULT_MODEL

API

I am testing out the Agents SDK and when running some of the basic demos, I could not figure out where model_settings.DEFAULT_MODEL is being set for an Agent.

Thanks

You can find the docs about Agents SDK and models here: Models - OpenAI Agents SDK

You can change the model like this:

spanish_agent = Agent(
    name="Spanish agent",
    instructions="You only speak Spanish.",
    model="o3-mini", 
)

I also couldn’t figure out where the default model is being set.

Thanks. That Models documentation is very helpful.

Hi, I saw that in their source code, the DEFAULT_MODEL is defined in the src/agents/models/openai_provider.py script on the line 11:

DEFAULT_MODEL: str = "gpt-4o"

I guess that is the one used when no other model is specified via the model parameter in the Agent class
