# Jev (🧠 Models)

[Home](https://abovethefog.app/index.md) › [Topics](https://abovethefog.app/topics.md) › Jev

Jev is 🔥 Hot on Above the Fog’s AI hype radar: a hype score of 72 out of 100 on Sep 27, 2026, 28 points lower than 7 days before. It has been in hype for 16 days, since Sep 12, and peaked at 100 on Sep 17.

TypeSafe AI's 'System One' model (launched Sep 15, 2026): instead of generating text, it returns typed, calibrated decisions, much faster and cheaper than an LLM.

## Where the attention comes from

“Normal” is the median of the source’s previous 14 normal days for this topic. A source is above normal when its value is at least 30% over that level and stands out from its usual day-to-day variation (z ≥ 2); the share is the part of the hype score that source explains. “× normal” is left blank when the normal level is 0.
