Describe someone else's financial document to me

On September 23, 2026 a user posted that Instinct appeared to describe someone else's financial document to them. Founder Noah Shinn responded the same day that the model had fabricated a proper noun — a hallucination, not a data breach — and that the team built a hallucination detection layer within 48 hours.

This one went wrong. Read what happened so you don’t hit the same problem.

How it works

  1. User interacts with the agent about a document
  2. Agent describes a financial document that appears to belong to someone else
  3. User posts the scare publicly
  4. Founder attributes it to a fabricated proper noun
  5. Team ships a hallucination detection layer in 48 hours

Why it’s worth knowing

A hallucinated name looked exactly like a cross-user data leak.
