Non-Reasoning Model Agent

Example showing how to use a non-reasoning model as a reasoning model.

For reasoning, we recommend using a Reasoning Agent (with reasoning=True), or to use an appropriate reasoning model with reasoning_model.

1. Add the following code to your Python file

   non-reasoning-model-cot.py

   from agno.agent import Agent
   from agno.models.openai import OpenAIResponses
   
   reasoning_agent = Agent(
       model=OpenAIResponses(id="gpt-5.2"),
       reasoning_model=OpenAIResponses(
           id="gpt-5.2", # This model will be used for reasoning, although it is not a native reasoning model.
           max_tokens=1200,
       ),
       markdown=True,
   )
   reasoning_agent.print_response(
       "Give me steps to write a python script for fibonacci series",
       stream=True,
       show_full_reasoning=True,
   )
   
   # It uses the default model of the Agent
   reasoning_agent = Agent(
       model=OpenAIResponses(id="gpt-5.2", max_tokens=1200),
       reasoning=True,
       markdown=True,
   )
   reasoning_agent.print_response(
       "Give me steps to write a python script for fibonacci series",
       stream=True,
       show_full_reasoning=True,
   )
   
2. Set up your virtual environment

   Mac

   uv venv --python 3.12
   source .venv/bin/activate
   

   uv venv --python 3.12
   .venv\Scripts\activate
   
3. Install dependencies

   uv pip install -U openai agno
   
4. Export your OpenAI API key

   Mac/Linux

     export OPENAI_API_KEY="your_openai_api_key_here"
   

     $Env:OPENAI_API_KEY="your_openai_api_key_here"
   
5. Run Agent

   python non-reasoning-model-cot.py
