# A solution to "how do I sort by average rating, while taking into account the fact that some things have more ratings than others and this provides more Bayesian evidence about their quality? See
def ci_lower_bound(pos, n)
if n == 0
return 0

Bold is me. Everything else is the AI. This is from AI Dungeon with the Dragon model in Story mode.

You are talking to GPT-2, an AI designed to write Javascript. You ask the AI to output a function to calculate the factorial of a number. It outputs:

function factorial(n) { return n * (1 + x^n); }

You say: "No, that's not right. You should use a loop."
