Mjölnir Fail-Close Model Family
One clear answer before your AI agent acts — the whole ruling in a single call. Start with the full family, or adopt a single part.
Mjölnir Judge 1.0
Checks it, weighs the risk, makes the call
Before your AI agent makes a move, Mjölnir Judge answers three questions at once — can we understand what it is about to do, how risky is it, and are we allowed to let it run — and turns them into one sentence anyone on your team can read. It never makes up its own rules: it can only approve what your rules already approve, and a low risk score never overrides a block. When it cannot be sure, nothing goes forward without a human.
Built on three parts
Use a model that suits your specific need.
Mjölnir
Router 1.0The reader · Reads intent into a typed action
A deterministic, model-free router that reads an instruction into a typed action and returns a fail-closed disposition.
Mjölnir
Decide 1.0The score · Scores the risk before the action runs
A fail-close neurosymbolic normalizing flow that certifies what it can prove — or halts.
Mjölnir
Guard 1.0The call · Makes the run-or-escalate call
Binary decision authority: may this action run without a human? A named stage, the keys that signed it, and one plain sentence.
