Definition
The cookbook ranks 182 skills across 33 categories in one Choice question plus three gate Nouls, then re-reads the top three in a second call. Over 488 requests, wrong skill loads fell from 16.8% to 7.3% and needless loads from 9.8% to 4.0%, against oracle floors of 2.5% and 1.2%.
It fixed 37 covered requests but broke 7 the agent had right, a reminder that a confident wrong suggestion is persuasive. The winner is appended as one system-prompt line after the roster so the prefix cache still holds.

Claude Code, Codex, and pi plugin plus MCP server and npm library that hands steps needing no text output to Jev: one batched call answers typed questions about a state, and an opt-in PreToolUse gate can only deny or ask.

After co-inventing ChatGPT, I kept asking myself: why have superhuman chat models not led to AGI? I’ve spent the last 2 years in stealth building a new way to train models (RLCD), and a new type of frontier AI model that we are releasing today: Jev • 20-200x faster • 40-400x

I spent the last 8 hours building a viral post classifier with Jev. It's now better at spotting viral posts than I am. And it's as good as Fable 5.1, but 100x faster.
