vibeflip - A truly random coin flip

Aug 30, 2025 - By Max Scheijen

I got inspired by vibesort. What a nice way to sort a array of numbers.

Which made me think of what other thinks are hard. A computer creating randomness. Can we maybe leverage LLMs?

So what is vibeflip?

It's a python library that facilitates a truly random coin flip (true or false) using a LLM.

from vibeflip import vibeflip

result = vibeflip()
print(result)  # True or False
pip install vibeflip
