Master Jev AI in 20 min

Every prompt I used and all three datasets are in my free newsletter: https://rakhulkarthick.substack.com/p... Jev is a new AI model from TypeSafe that can't write a single sentence. It answers your questions with a number that says how sure it is. I set it up from scratch and built three real things with it. A lead sorter for 53 real Upwork jobs. A fair speed race against Claude on 20 real complaints. And an inbox sorter that only asks a bigger model when Jev isn't sure. TypeSafe's homepage says 193.6x faster. In my race, Jev was 6.4x faster and 65x cheaper than Claude Opus 5.5.
