Use the current default model

The preserved cookbook block uses Chat-format text and image_url parts, but Agent() currently defaults to OpenAIResponses. That adapter expects Responses content types. Save this complete version as input_formats.py for the run steps below; Agno converts Image to the model's input format:

input_formats.py — current adaptation

from agno.agent import Agent
from agno.media import Image

agent = Agent()
agent.print_response(
    "What's in this image?",
    images=[Image(url="https://upload.wikimedia.org/wikipedia/commons/thumb/d/dd/Gfp-wisconsin-madison-the-nature-boardwalk.jpg/2560px-Gfp-wisconsin-madison-the-nature-boardwalk.jpg")],
    stream=True,
    markdown=True,
)

To keep the original Chat-format dict instead, import OpenAIChat from agno.models.openai and construct Agent(model=OpenAIChat(id="gpt-5.2")).

Run the Example

Set up your virtual environment

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

Install dependencies

uv pip install -U agno openai

Export your OpenAI API key

export OPENAI_API_KEY="your_openai_api_key_here"

Run the example

Save the current adaptation as input_formats.py, then run:

python input_formats.py
