Your AI Test Engine, in a Box You Can Lock in a Room

Every AI testing tool has a quiet problem it would rather you didn't think about: to use it, you ship your source code to someone else's servers.

For a side project, fine. For a hospital, a bank, a defense contractor, or anyone whose code is the crown jewels — it's a non-starter. "We encrypt it in transit" doesn't pass an audit. The only answer a regulated buyer accepts is: our code never leaves the building.

So we built QuantumVerifi to give exactly that answer — and to make it practical, not theoretical. Here's how.

The whole engine fits in a box you own#

The instinct in AI is to reach for the biggest model. We did the opposite. We deliberately chose the smallest model that's good enough once it's specialized — a 7-billion-parameter coder model — for one reason:

A 7B model fine-tuned on your team's actual passing tests beats a giant generic model at your specific task — and, crucially, it fits where a frontier model never could.

How small? We run the entire flywheel — training and serving — on a 16GB consumer gaming GPU today. Step up to an NVIDIA DGX Spark — a desk-sized AI computer with ~128GB of memory for around the price of a laptop — and it's downright roomy. You can put one in a locked server room and run a self-improving test engine for your whole org, with the internet cable unplugged.

Think of it this way: a frontier model is a Formula 1 car — incredible, but it needs a pit crew, a track, and a fuel budget. Our specialist is a purpose-built delivery van — it does your job superbly, parks in a normal garage, sips fuel, and you can hand the customer the keys.

Zero arrows leave the building#

In a sovereign install, every link in the chain runs on your hardware:

• Training runs on your GPU.
• The model that writes your tests is your fine-tuned model, served on your GPU.
• Even the fallback — the model used when needed — is a local model, not a cloud API.

The result is a data-flow diagram with no arrows leaving your network. Your source code, your tests, your dataset, and your model all live and die inside your firewall. Not "we promise not to look" — physically unable to leave, enforced by a default-deny network policy your own security team can verify.

For code analysis, this is completely clean: nothing external is ever needed.

The part most people miss: your data is the real asset#

Here's the strategic punchline.

Every time QuantumVerifi generates tests, it doesn't just hand them over — it runs them in a sandbox. Only the ones that actually pass become training data. That means your dataset isn't scraped or synthetic or noisy like most fine-tuning data. It's execution-verified: real prompts paired with outputs proven correct by execution. That's the highest-quality training signal there is. It's gold.

And it's stored in a clean, model-agnostic format — the same universal format any model can learn from. Which leads to the thing that makes this future-proof:

Models get deprecated every few months. Your verified dataset doesn't. When a better base model ships — a new Qwen, a new Llama, a 200B open model, whatever comes next — you don't start over. You point training at the new model and instantly get a better specialist, from the same gold data. The smallest model or the most gigantic one: same dataset, you just retrain.

You're not locked to a vendor's model. You're not locked to a vendor's cloud. You own the one thing that compounds.

Why this matters#

Put the three ideas together and you get something no "AI writes your tests" tool can match:

• It's specialized — it learns your codebase's style and gets better every run.
• It's sovereign — your code never leaves your network.
• It's small — which is the only reason the first two are actually deployable. One box, on a desk, inside your firewall.

Cost savings are real — no per-token fees, scales to zero when idle. But for the customers who need this most, cost is the third-best reason. The reason they sign is simpler:

Their crown jewels never leave the building — and the engine that guards them gets smarter every single day.
