Question about OpenAI Agent equipped with GPT-5

Hi, I am currently using the below code, but my agent becomes slower than when I using GPT-4.1.

Agent_I = Agent(
    ## INPUT INFORMATION AGENT QA AGENT
    name="Input Information Agent",
    instructions=instruction,
    model=GPT-5,
    output_type=InputQAOutput
)

I believe that reasoning process takes long time.
How can I turn off reasoning while using GPT-5 with the above code?

Thanks,

if you add this parameter it will fix that

reasoning={
        "effort": "minimal"
    }

Thank you for your help. I just tried, but failed.
I got this error.
```

      5     model="gpt-5",
      6     reasoning={"effort": "minimal"},
      7     output_type=InputQAOutput
      8 )
   (...)
     24     output_type=GenerationOutput,
     25 )

TypeError: Agent.__init__() got an unexpected keyword argument 'reasoning'

This agent comes from OpenAI agent SDK.

from agents import Agent

Where should I put that parameter?

Thanks,

with the Agents SDK you can use the model_settings parameter to include the resoning effort. like this:

model_settings=ModelSettings(
        reasoning={
            "effort": "low"
        }
    )

I noticed that if you are using the fileSearchTool, the effort: minimal wont work, but low does.

Hope it helps :slight_smile:
