Eight days.
Public git.

AqtaBio publishes its spillover forecasts to a public git ledger before the outcome window closes. Here is the most recent proof.

This is the pattern across Aqta. Receipts you can verify without us, signed before the moment they matter.

Bounds + AqtaCore

How the full stack works

Sensitive data is removed on-device before it reaches the model, with an on-device record of what was stripped. AqtaCore then signs the governed call, so an auditor can verify that decision receipt offline and review the redaction record alongside it.

  1. 01The input

    A sensitive document

    Personal data you cannot send to a model as is.

  2. 02On-device

    Bounds strips PII and logs what it removed

    Redacted on-device, with an unsigned record of what was removed. PII never leaves your device.

  3. 03The gateway

    The clean document enters your LLM via AqtaCore

    One gateway in front of every model provider.

  4. 04The receipt

    AqtaCore signs the call and what the model decided

    A receipt per call: request hash, policy applied, model, outcome. Signed with Ed25519.

  5. 05The audit

    An auditor verifies the signed receipt offline

    Receipt B verifies against one published key. The redaction record is reviewed alongside it. No call back to us.
