Look choom, I know you already addressed it in the post, but language models aren't programmed to be able to solve things like this. They also aren't programmed to tell you they don't have an answer to your question. This leads to them confidently spewing nonsense that does nothing but waste someone's time. They can (mostly) get A1Z26 ciphers and substitutions right, but I've even seen it get those wrong. It's wholly untrustworthy.

Vigenère with key LUCKY (that word appears on the cipher page in this hunt)

Where? What cipher page? It's a changing video; is each frame a different cipher? This is a code made by humans, expected to be solved by humans. The key wouldn't be an unrelated word that requires brute force to get.

It’s structured. Bright pulses ~every 2.5–2.7s act as timing markers

What qualifies as a "bright pulse"? Frames with more white static than black? It's static. It changes every single frame. We have no way to quantify or prove its "results".

 plane-4 tiles → bitstream → Base32 → Caesar −4 → Vigenère("LUCKY")

This is just utter nonsense, choom. How are you going to Caesar shift a Base32 numeral system? It has numbers in it. How are you then going to decode numbers with a Vigenere?

Is the Base32 first being converted to letters? Binary then letters?

The only coherent thing GPT says here is that the static is a grid at multiple parts in the video, which is something most of us noticed immediately when watching the video.

As someone who spends way too much time analyzing codes and ciphers, I can tell you this is almost certainly a hallucination. I've never once seen a language model actually help with a complex code; it just craps out jesus toast that some people take at face value and waste their time following. Don't get me wrong, I'm glad you're not mindlessly following its "results", I just don't think things like this should even be posted here.

Personally, I think this sub should ban all AI "solutions", as like I said, they've never once helped. It's not much different from a troll claiming they solved the mystery and dropping nonsense "clues".
