PatternsStructured-data-extraction cascade
SDE cascade
A two-stage extraction cascade: a mini model extracts, a Noul battery verifies, and a confidence gate escalates to a reasoning model.

Definition
The pipeline runs gpt-5.4-mini for extraction, verifies each field with one battery of Noul questions in a single call, and escalates to gpt-5.5 when the gate reads 0.7 or below. On an internal 100-prompt sweep it sat up-and-left of every single model on the cost/quality chart.
Its cautionary example is a jsonschema-valid but semantically wrong record that passed validation, showing that verification questions catch errors a schema cannot.

Real-time Clippy that wakes up when you struggle
I built real-time Clippy with Jev. It quietly watches how you use the product and only wakes up when it thinks you’re struggling. Hesitating? Confused? Stuck? Clippy knows. Even its reactions are controlled by Jev. 👀

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.
