5 real things people did with Grok, with the source and a prompt to try it yourself.
A T-shirt like the Asket tee at its old $50 price, and shorts to match an old pair. Grok invented a few review claims on the way, but both picks turned out right.
Result Both picks matched; the shorts cost less
Their own code, their own database, on their own laptop. OpenAI's models and Claude found the issues but refused to confirm them. Grok tested that they were exploitable and suggested a fix.
Result Tested on their own copy, fix proposed
lldb behaved differently through Python in Docker than on their own Linux box. Grok 4 traced it to how address sanitizer works in each environment. They're impressed so far.
Result Traced to address sanitizer differences
The repair cost too much, so they gave Grok a must-have list: low mileage, big trunk, 40+ MPG, under budget, near the dealer. It found a 2020 Ford Escape Hybrid.
Result They accepted maybe missing $3000 in savings
The script came out almost perfect on the first try, except for a one-character typo in the file-path code. Finding it took an hour: the hidden cost of code that's nearly right.
Result Close to really good, frustrating when wrong
