Lower AI costs.
Raised standards.

Frontier models are expensive. Smaller models don't always get it right. With Kadari, there is no compromise: verifiable proof that optimizes costs and reduces risk.

proof

We prove it
before we count it.

Kadari is a verification layer for your LLM spend: a deterministic judge proves a smaller model would have matched your frontier model's answer — on your own quality bar — so you lower AI costs with evidence, not promises.

Three numbers you can act on: what you spend today, what the identical answer costs for less, and what the difference becomes at scale.

Same result, a smaller bill — measured, not guessed.

Proof, not promises

We don't estimate a saving and ask you to believe it. We prove a smaller model would have matched the answer you'd get today — don't commit to promises, commit to the proof.

case study · support triage

Track every decision

Customer support is one example of the work Kadari can prove. For every real answer, Kadari's judge confirms whether a smaller model would have produced an equivalent response and flags the ones it can't. If we can't back a number, we refuse to take the risk.

Replay any decision

Pull up any request and see exactly how the judge ruled. The same inputs give the same verdict today, next week, or in an audit a year from now.

Savings with the math shown

Not just “you saved.” You see what each answer cost on your trusted model, what it would have cost on a smaller one, and the difference.

Your quality bar, in view

You set how often a smaller model has to match your trusted model. That bar sits beside your measured match rate, so “are we safe right now” is always answerable.

We have no customers yet, so there's nothing live to show — and we'd rather say so. This is how a Kadari trace reads, run on a synthetic workload. Yours would come from your own traffic.

How Kadari's judge decides

Fig. 04 — The Twin Check

For each real request, the judge weighs your model's answer against the answer a smaller model would produce — projected, never run. Only when it can prove they would match is the saving counted; on any doubt, the request stays on your model.

Logs to Proof
in Four Steps.

01

Wrap

Two lines around your existing client. Your app runs exactly as before — nothing is re-run, nothing is auto-uploaded.

02

Observe

With only one shared log, Kadari finds the high-volume work a smaller in-family model could likely handle.

03

Prove

A deterministic judge proves a smaller model would have matched your trusted model's answer. We keep it on your model on any doubt — and only count what passed.

04

Show

What was safe to cut, what we left alone, and exactly where a smaller model would have differed. Everything surfaced and never hidden.

Where the work routes

your provider, your models

Your provider. Your models.
Our receipts.

We built Kadari on the principle of cost optimization without gambling on quality or fully exposing data. We don't sell a model or push you toward one. Our focus is to show you where your spend goes and prove what's safe to cut. Backed by numbers and always-on rigorous testing.

NEUTRAL

A referee, not a vendor

Model neutrality is fundamental to our business because we don't give favors or try to upsell anything.

Independent by design.
VERIFIED

We measure equivalence, not vibes

Every saving is checked against your current model's answer, scored by a version-pinned judge. We claim a bound you can audit, never “lossless.”

Bounded equivalence, on your own criteria.
OBSERVABLE

The decision trace is the product

For any request you can open the full trace: your model's answer, the judge's verdict that a smaller model would have matched it, what it would have cost, and when sampled, the exact diff we checked. Replayable to the same verdict later, by an auditor.

Reproducible against its snapshot.
SAFE

Route up on any doubt

Set a quality floor we can never cross, then dial how hard we chase savings above it — one switch turns us off entirely. The instant we're unsure, we stay on the model you trust, inside your provider and contract. We never switch you across providers.

Default-up. Your floor. Intra-provider only.

Wrap one call.
Nothing else changes.

Kadari ships one thing: a lean, zero-dependency Python client that records the calls you already make — to a local log, on your own machine. It never alters the call and carries none of our analysis engine. We send design partners the wheel directly; install it offline in one line.
