Nice work once again from Ofir Press and team; this seems to be an idea that's in the air.
> Our 200 tasks range from compact CLI tools to widely used software such as FFmpeg, SQLite, and the PHP interpreter. We evaluate 9 LMs and find that none fully resolve any task
Fwiw, this is very different from what we find in MirrorCode:
> Opus 4.6 successfully reimplements almost every program up to gotree’s size in our benchmark.

I don't have time right now to dig in to what could explain the difference (I'm working hard on getting the full MirrorCode out as soon as possible). But I suspect that the ProgramBench authors are either under-eliciting the AIs, or their tasks are unfair/impossible given the constraints, or both.
I hope to look more into it after releasing MirrorCode, and write up my conclusions.
