I know it's a single data point, but yesterday I showed it a diagram of my fairly complex micropython program, (including RP2 specific features, DMA and PIO) and it was able to describe in detail not just the structure of the program, but also exactly what it does and how it does it. This is before seeing a single like of code, just going by boxes and arrows. The other AIs I have shown the same diagram to, have all struggled to make sense of it.
