Jev: The ChatGPT Co-Creator's System One Model Can't Talk
Diogo Almeida, who co-invented RLHF and InstructGPT at OpenAI, spent two years building Jev: a System One model that cannot generate text, only typed decisions with calibrated confidence. TypeSafe AI prices input at $0.042/MTok, output free, running 70-500ms. Automation needs a model it can trust, not one that talks.
Show a model your old code and it writes your old bugs: 32 runs, 0% reuse
Same task, same models, two commits of my own repo. From the pre-migration commit every run hand-rolled a 190-line typeahead with the exact defects the migration removed; from the post-migration commit every run reused the shared component in 41 lines.

The gate couldn't read my JavaScript, so I removed the numbers from it
A publishing gate that blocks any unsourced number on a page cannot read inside a script tag, which breaks the moment a page needs a JavaScript calculator. Instead of teaching the gate to parse JavaScript, or exempting scripts from the check, I restructured the calculator so its JavaScript never contains a domain number at all — rates arrive through the DOM already verified, and a numeric-literal whitelist makes the workaround structurally impossible. This piece walks through the invariants and tests that make that enforceable rather than aspirational.

68% of Google Searches Now End Without a Click. Your Analytics Cannot See What You Lost.
