The site describes CalcGPT as an art installation

As a critique of AI, it probably is pretty effective - no better way of mocking ChatGPT than by having it fuck up basic arithmetic that even a five-year-old can do.

You wanna mock somebody, it helps tricking them into mocking themselves.

it cannot handle subtraction going negative

Let’s just say that negative numbers remains a mystery for LLMs.

My favorite part is that as with all LLM solutions it either spits out the correct answer or absolute nonsense. This calculator will never have a floating point error or screw up the order of operations, but it will sometimes decide that 2+2 equals “either 5 or 4.0000354, depending on how you measure it” even on the minimally-spicy settings.

Lol that regenerate button on a calculator. Amazing.
