Highlights
- Seven Choice questions read the date's shape and parts, month, day, year 1900 to 2050, and weekday, while the model does no math.
- Code resolves the parts against a pinned TODAY and infers missing years; five of six examples were auto-accepted.
- An absent kickoff date returned none with 0.46 confidence and the note that the absolute date was incomplete.
- Bare weekdays mean the next occurrence on or after today; next means the following calendar week.
Watch out
Phrases like next Thursday are ambiguous, so the code fixes a convention and sends anything under 0.60 confidence to review.

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
