Vext Labs, Inc. · AI research

We grow a mind that doesn’t forget — and prove what it did.

The lab behind JUWEL. Two programs: memory that grows without forgetting, and action receipts anyone can verify — without trusting us.

Don’t take our word — break it. One byte and the math fails. Never trust. Check.

Ship the proof.
Grow the mind.

STOA · receiptsshipping · open source

A receipt whose verifier isn’t the vendor.

Every JUWEL action is signed and Merkle-chained into a receipt you check offline, against an open verifier we don’t control. Flip one byte and the math fails. This half ships today — it anchors the product.

CIP · continual learningresearch · toy-scale

Toward memory that grows without forgetting.

The open experiment: a learner that adds skills without erasing old ones. Today it survives toy-scale curricula — arithmetic, not the real world. That test is still ahead, and we publish either way.

substrate-agnostic by design — the receipt proves what ran

Published either way.

note 07 · stoaReceipts, not logs: neutrality as a propertyWhy an audit trail only counts if the verifier isn’t the vendor — and how offline falsification changes the trust math. See it live on the JUWEL landing. note 06 · cipForgetting curves on toy curriculaWhat survived, what didn’t. Honest results from arithmetic-scale continual learning — including the failures. Full write-up publishing soon. note 05 · systemsSubstrate-agnostic by designJUWEL runs on the substrate that fits the job; the receipt records what ran. No wrapper claims — just the record. Read the architecture.
04 · about the lab

A small lab with one rule.

If we can’t prove it, we don’t claim it. If we tested it, we publish it — including the failures.

who we areVext Labs, Inc.An American AI research lab, incorporated 2026. We build JUWEL — the product where the research meets the real world — and the open verifier that keeps us honest.
what ships todayThe proof layerSigned, hash-chained receipts (ECDSA P-256) for every agent action, checked offline by an open-source verifier we don’t control. Real now, in JUWEL and JUWEL OS.
what we're growingThe memory programCIP — continual learning toward memory that grows without forgetting. Passed toy-scale tests; the real-world test is still ahead. We publish either way.

The research, wearing a face.

JUWEL is where both programs meet the real world — she does the job, signs the receipt, and you check it yourself.
