Know when your
model knows.
Typed uncertainty for any classifier. Every prediction returns CERTAIN, PARTIAL, or UNCERTAIN.
Loan application assessment — 3 sample predictions:
approve
approve / deny
insufficient evidence
The problem
Confidence scores lie.
Your model says 90% confident. It's wrong. You approved the loan, shipped the part, cleared the patient. The confidence score told you what to believe. It didn't tell you what to do.
Traditional classifier
90% confidence
Wrong. Approved a bad loan.
Cost: $47,000.
Tercet
Flagged for review. Analyst catches it.
Cost: $0.
How it works
Three types. Not a score.
Every prediction tells you what to do with it — not just what it thinks the answer is.
Commit
The model is certain. One class has decisive evidence. Auto-decide.
67% of predictions · 99.2% accuracy
Narrow
Evidence supports 2–3 classes. The model narrows it down. Human picks from a shortlist.
26% of predictions
Abstain
Not enough evidence. The model says so before you waste time. Route to a specialist.
