Image Generation Agent

The source-fidelity code uses OpenAIChat and gpt-image-1 despite its Responses category. Replace them with OpenAIResponses and gpt-image-2 before running the example.

"""Example: Using the OpenAITools Toolkit for Image Generation

This script demonstrates how to use the `OpenAITools` toolkit, which includes a tool for generating images using OpenAI's DALL-E within an Agno Agent.

Example prompts to try:
- "Create a surreal painting of a floating city in the clouds at sunset"
- "Generate a photorealistic image of a cozy coffee shop interior"
- "Design a cute cartoon mascot for a tech startup"
- "Create an artistic portrait of a cyberpunk samurai"

Run `uv pip install openai agno` to install the necessary dependencies.

Run the Example

Set up your virtual environment

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

uv venv --python 3.12
.venv\Scripts\activate

Install dependencies

uv pip install -U agno openai

Export your OpenAI API key

export OPENAI_API_KEY="your_openai_api_key_here"

$Env:OPENAI_API_KEY="your_openai_api_key_here"

Use the Responses API

Replace the OpenAIChat import and constructor with OpenAIResponses(id="gpt-5.2").

Encode the image bytes

Add import base64. Encode response.images[0].content with base64.b64encode(...).decode("utf-8"), then pass that string to save_base64_data.

Update the image model

When saving the code, replace gpt-image-1 with gpt-image-2.

Run the example

Save the code above as image_generation_agent.py, then run:

python image_generation_agent.py
