o3 failed the first test I gave it. I wanted it to create a bar chart using Python of the first 10 Fibonacci numbers (did this easily), and then use that image as input to generate an info-graphic of the chart with an animal theme. It failed in two ways. It didn't have access to the visual output from python and, when I gave it a screenshot of that output, it failed in standard GenAI fashion by having poor / incomplete text and not adhering exactly to bar heights, which were critical in this case.

So one failure that could be resolved with better integration on the back end and then an open problem with image generation in general.
