Instinct says leaked-doc complaint was hallucination, not a data breach

A user accused AI assistant platform Instinct of describing a financial document that wasn't theirs and referencing a photo they never sent, asking founder @noahrshinn whether it was a data leak.

Instinct's response: the incident was caused by a hallucination (a fabricated proper noun) amplified by the model's casual thinking trace — not a breach, and no user-isolation boundary was violated. The company points to isolated sandboxes, short-lived local credentials, and identity-signed tool execution as its data-partitioning safeguards.

It also says it built an active hallucination-detection system within 48 hours, powered by small models that scan and verify every token for ungrounded claims, creative brainstorming in thinking traces, and rare sampling errors.
