You'll get 50% prediction accuracy for a fair coin no matter what result a model gives. Try testing adversarial games. Mixed strategies make actual sense in them.

Try it yourself to prove you’re useful. Predict my coin flip.

A probabilistic system that cannot reliably reproduce probabilities - somewhat ironic, but absolutely not its purpose.

That's like not using an LLM for coding assistance because it can't count r's in strawberry.

Try asking it to write a program to predict coin flips. That's what it is trained to do.

I'm dying to know if you got heads or tails when you flipped the coin.
