Reading last years entries, this image decompression oneliner outputs its own logo when passed the hash of its source code?! Pretty neat.

So everybody just LLM'd this, right?

I didn't find them useful when I wrote my entries. LLMs get confused with code that "looks like" other code, and that intentional misdirection is half the fun of a good IOCCC entry. Plus, the morality filters get annoying once you obfuscate the code. Plugging an unsubmitted entry into Gemini, it refuses to even explain it because it thinks it's malware.

LLMs can help you analyze the code, but not write it. Their ability to obfuscate is quite limited and uninspired. The last IOCCC was in 2020, so we've had plenty of time to work on it.

Vibe obfuscation, all the cool kids are doing it.

i guess that should make vibe de-obfuscation as easy

For an obfuscation comp, I love the fact they explicitly refer to and do not rewrite "index.html web pages for each winning entry".
