Managed AI quality · measure → improve → run cheaper

Your first real number for AI quality.

We run a managed quality loop on your production AI agents. You get a score you can defend, the fixes that move it, and smart API routing that typically cuts the model bill by half. You approve, we operate.

The loop · sold as a service

Measure it. Improve it. Prove the gain. Keep it running.

One managed loop on your production AI. We install the measurement, get paid to improve what it exposes, and keep the loop running so you never go blind again.

01

Measure it

Your first real quality number, on your real traffic. The platform stands this up out of the box.

Which checks fail, for which customers, and the root cause. Surfaced automatically.

Keep it running

Your system keeps changing. We keep it measured and routed, every month.

The platform runs out of the box, and it's what we can stand up for free. The managed service is our engineers improving the agent and operating the routing, every month.
What you get

Three answers every AI team is missing.

All the numbers below come from one coherent worked example: Aria, a customer-support agent measured on a public benchmark. The interactive demo walks the same story.

1 · Evaluate

Is it actually good, and is it slipping?

"We don't actually know if our AI is any good."

A test suite of 60 business-language checks built from your policies and graded on real conversations, every run. Aria scores 78 of 100 and climbed there over twelve weeks. When a model update quietly dropped quality in week 5, the suite caught it within days, before customers did.

Week 5 · quality dip detected Week 7 · fix shipped
2 · Optimize

Make it better without a rebuild.

"It gives customers wrong or made-up answers."

A handful of low-effort changes, each backtested against the suite before it ships. For Aria that meant quality 78 to 89 and wrong answers 9% to 3%, roughly 12,000 fewer bad answers a month at 200k conversations. The current model stayed. The gains came from how the agent is built.

3 · Cost efficiency

Cut the API bill by half. We run it.

"Our model bill doubles every time usage does."

Several routes lead to a lower bill: a cheaper backtested default, caching, token tuning. The biggest is managed API routing: classify every request in milliseconds and send it to the cheapest model that still passes your quality bar. For Aria the blended cost fell from $0.021 to $0.010 per conversation, a 54% cut with quality held on every tier.

The flagship service · managed API routing

Hold the quality, cut the spend.

A routing and caching layer we design, run, and tune for you. Quality held is the constraint; the savings are what's left. Most teams see the model bill cut by half or more.

1
Classify.A small, cheap classifier scores each request's difficulty in milliseconds.
2
Route.Simple requests go to a light model, standard to a mid model, and the frontier model only runs when a request earns it.
3
Cache.Stable system and knowledge-base context is reused, and repeat questions are served from cache.
4
Guard & tune.Quality is scored per tier against the same test suite. If a tier slips, traffic falls back to the safe model automatically, and we re-tune as your traffic changes.
What you do
Approve the quality bar and read a monthly report. The building, staffing, and babysitting is ours.
Model-agnostic
One router across OpenAI, Anthropic, Google, and open-weight models. When a better price-per-quality option ships, we backtest it on your traffic and fold it in.

Why managed

Your ML team knows how to do all of this. They don't have the quarter.

Everything here can be built in-house. The comparison is what it takes to keep it running while you also ship product.

FAQ

The questions we always get.

Are the numbers on this site real?
They are a worked example: a customer-support agent measured end to end on a public benchmark, kept deliberately consistent across this site and the interactive demo. They show the method. A sample audit produces the same views from your own logs.
Will routing to cheaper models make quality worse?
Quality held is the constraint, the savings are what's left. Every tier is scored against the same test suite as your main model, and if a tier slips, traffic falls back to the safe model automatically. In the worked example the bill fell 54% with quality held on every tier.
How long until we see our own numbers?
Days. A read-only connector on day one, a first defensible score by about day three, and a full readout with a weak-spot map and routing savings estimate by day five.
Which models and providers do you support?
The loop is model-agnostic: OpenAI, Anthropic, Google, and open-weight models behind one router. When a better price-per-quality option ships, we backtest it on your traffic before any of it goes live.
What does it cost?
The measurement build is free: it is how we earn the right to the rest. Improvements are scoped projects, and the ongoing loop plus the routing layer run on a monthly retainer that is typically a fraction of the API spend it saves.
Is this replacing our support team?
No. It makes the AI you already deployed trustworthy and cheap enough to handle the easy contacts well, so your people spend their time on the hard ones.
