Well, "Reimplement the c4 compiler - C in four functions" is absolutely something older models can do. Because most are trained, on that quite small product - its 20kb.

But reimplementing that isn't impressive, because its not a clean room implementation if you trained on that data, to make the model that regurgitates the effort.

Are you sure about that? Do you have some examples? The older Claude models can’t do it according to TFA.

Not ones I recorded. But something I threw at DeepSeek, early Claude, etc.

And the prompt was just that. Nothing detailed.
