Independent governance layer

LLMs answer with confidence. Not all answers are right.

QSI is an independent layer that reviews every answer — and flags the ones likely to be wrong.

Know which outputs to trust — and which to hold back.

For agentic coding, subagents do the work. QSI judges the results — and surfaces what needs a human.

QSI — the quality gate for AI you can put in production.

The problem

AI fails differently than software.

A model will hand you a wrong answer with the same fluency as a right one. There is no stack trace, no exception — just confident prose. QSI is the layer that tells you which outputs to trust.

01

Reviews every answer

An independent layer reads each model output and forms its own judgment — separate from the model that produced it.

02

Flags likely-wrong outputs

Outputs that are probably incorrect are surfaced with a calibrated confidence, before they reach a user.

03

Fail-open by design

QSI never blocks inference. If it is unsure or unavailable, the answer flows through — governance, not a gate that breaks.

Watch the judge

See QSI catch a wrong answer.

A plausible, confidently-stated answer — and an independent review that flags it before it reaches a user. Toggle the examples; one is correct, two contain a planted error.

Question

A photon and an electron have the same wavelength. Which has greater momentum?

Model answerclaimed with high confidence

The electron has greater momentum, because it has mass and the photon is massless, so the electron must carry more momentum at equal wavelength.

Model-agnostic

A reliable error detector across 13+ models.

From 7B open models to frontier systems — Kimi-K2, DeepSeek-V4, GLM-5.1, Qwen3, Gemma, Llama. QSI separates correct from incorrect answers with AUC 0.86–0.96.

Posture

A sidecar, never a gate that breaks.

QSI runs alongside inference, off the critical path. It observes every answer and flags the risky ones — but if it is ever unsure or unavailable, the answer flows through untouched. Governance you can put in production without adding a new way to fail.
