Where's the raccoon with the ham radio? (ChatGPT Images 2.0)

This article tests OpenAI's newly released ChatGPT Images 2.0 (gpt-image-2) image generation model, comparing it with the older gpt-image-1 and other models like Google's Nano Banana 2 and Pro. The author uses a 'Where's Waldo' style prompt asking for a raccoon holding a ham radio, then analyzes the results from each model, noting improvements in image quality and detail. The post includes technical details on using the OpenAI Python client library, output settings, and dimensions. It is a tech-focused review of AI image generation capabilities.
