AI Authorization Is Not Observability
Most AI tools tell you what happened after the model call. Permisyn decides whether the call is allowed before the provider sees it.
The gap
Tracing, evals, gateways, and dashboards are useful, but they are not authorization. A risky model call has already happened by the time the alert arrives. Permisyn moves the allow/deny decision into the traffic path: authorize, deny, meter, sign, and prove.

The core question changes from 'what happened?' to 'was this allowed to happen?'

Why it matters
Test findings
No in-process library needs installing in every application team's codebase.
Permisyn does not need to store the upstream provider key.
Permission is enforced before the upstream provider receives traffic.
Passport and cost-cap rules are blocking controls, not notifications.
Every authorized call becomes signed evidence with a public proof surface.
