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 by creating a Where's Waldo-style image featuring a raccoon holding a ham radio. The author compares results from the older gpt-image-1, Google's Nano Banana 2, Nano Banana Pro, and the new gpt-image-2 model. The post includes technical details on using the OpenAI Python client library, setting output quality and dimensions, and analyzing the generated images for the hidden raccoon. It provides a hands-on evaluation of the model's capabilities and limitations.
