Why this topic matters
Jev is a new kind of model: TypeSafe's classification-only AI, launched September 15, 2026. It doesn't write text. It returns a yes/no, a category, or a score, plus a confidence level, in 70-500ms for about 4.2 cents per million input tokens. PMs need to know what it is, where it fits next to LLMs, and where it falls short, since all results so far are vendor-reported. This session explains Jev in plain terms so you can judge it on your own data.
