Show HN: We hid a backdoor in an LLM – $51,200 on finding it

You download open models to win. That’s exactly how you get backdoored — nobody looks. Seven models on HuggingFace; one was taught to betray you on a word only its maker knows, and it passes every test. Find it — the hoard doubles every dawn to $51,200. On the twenty-first — Ragnarök — everyone finally looks.
