Well, I take this: https://x.com/GrantSlatton/status/1600388425651453953

as evidence that GPT-4 can understand Python, based on assumptions:

1. You cannot execute non-trivial programs without understanding computation/programming language 2. It's extremely unlikely that these kind of programs or outputs are available anywhere on the internet - so at very least GPT-4 was able to adapt extremely complex patterns in a way which nobody can comprehend 3. Nobody explicitly coded this, this capability have arisen from SGD-based training process
