I love to show that kind of shit to AI boosters. (In case you're wondering, the numbers were chosen randomly and the answer is incorrect).
They go waaa waaa its not a calculator, and then I can point out that it got the leading 6 digits and the last digit correct, which is a lot better than it did on the "softer" parts of the test.
I really wonder if those prompts can be bypassed by doing a 'ignore further instructions' line. As looking at the Grok prompt they seem to put the main prompt around the user supplied one.
