Impossible GPT Apps

I've tried and failed miserably at making two GPT apps.

1. A chess game which shows the visual state of the board after every move (as a DALL-E 3 image).

2. A TensorFlow visualizer, which takes a model summary plot image as input, and displays a new plot with the nodes properly represented (I feel that I could have made this work w/ a bit more effort, but decided it wasn't worth it).

But it does make me think that these apps are kind of gimmicky and I don't really understand how they are much better than just asking ChatGPT questions directly, despite the fact that they have their little self-contained instructions and fine-tuning.
