AnonRouter vsBLACKBOX AI
Blackbox sells enterprise inference on a zero-retention promise. AnonRouter makes the same promise, publishes the code that keeps it, and lets you check it before you have spoken to anyone.
What’s the difference between AnonRouter and BLACKBOX AI?
Both services route across a large model catalog and both lead with privacy. The difference is whether the guarantee is something you are told or something you can test. Blackbox offers dedicated single-tenant inference and a router across a large catalog, aimed at enterprise teams deploying at scale. AnonRouter puts a strict content-retention boundary and privacy-aware routing layer between your application and 200+ models, verifiable before you commit to anything.

At a glance
AnonRouter vs BLACKBOX AI
Seven things AnonRouter does that a closed enterprise platform does not. Every row is a capability, not a setting you have to trust someone to leave switched off.
Source of the code handling prompts
AnonRouter
Yes. Apache 2.0, including every component that can touch plaintext.
Blackbox
No. The inference platform is closed source.
Verifying the privacy claim
AnonRouter
Yes. Pull the enclave attestation with the SDK and check it against the published build.
Blackbox
No published attestation. The claim rests on documentation and contract terms.
Privacy without an enterprise agreement
AnonRouter
Yes. The same boundary applies to a $5 top-up and to production traffic.
Blackbox
The strongest handling is framed around enterprise deployment.
End-to-end encrypted routes
AnonRouter
Yes, wherever the provider runs an enclave. The router holds no key.
Blackbox
Encryption in transit, but no route where the platform is unable to decrypt.
Identity separated from request content
AnonRouter
Yes. A ticket flow splits account identity, plaintext, and provider credentials.
Blackbox
No. Usage sits under an organization account.
Privacy floor on automatic routing
AnonRouter
Yes. /auto stays inside a privacy boundary and fails closed when nothing qualifies.
Blackbox
Routing optimizes for cost and capability rather than a retention guarantee.
Account without an email address
AnonRouter
Yes. Private accounts open with a recovery phrase instead of an inbox.
Blackbox
No. An organization account is required.
Claim versus proof
The claims are similar. What backs them is not.
Blackbox states that it retains zero data and that your prompts are not its product. We say the same thing, which is exactly why saying it cannot be the differentiator.
The privacy claim
AnonRouter
No content retention, enclave-backed handling, and E2EE routes where the router holds no key.
Blackbox
Zero data retention, encryption in transit, and training opt-out enforced upstream.
What backs the claim
AnonRouter
Published source for every component inside the enclave, plus a hardware attestation.
Blackbox
Product documentation and, for enterprise terms, a contract.
How you check it
AnonRouter
Run the SDK, pull the enclave's attestation, and compare it against the published build.
Blackbox
Read the marketing page, then negotiate terms.
How you get started
AnonRouter
Create an account, top up, send a request. A private account does not need an email address.
Blackbox
An enterprise motion aimed at teams deploying at scale.
Who the request belongs to
AnonRouter
A ticket. The system that knows your account and the system that sees content are separated.
Blackbox
An organization account under an enterprise agreement.
Read the code that handles your prompt
Inspect the code that handles request content, then use the verification SDK to check a supported confidential route.
Why AnonRouter
Privacy is part of the architecture
The value is not only access to models. It is what the router is structurally unable to retain.
Audit the router instead of trusting it
Every component that can touch prompt plaintext is published under Apache 2.0, and the SDK checks the enclave's attestation against that build.
Remove prompt logging from the product
Prompts and responses are never written to disk. There is no router-side content logging switch to enable later.
Know what you pay
Model usage is billed at listed rates. Credit purchases include a separately disclosed platform fee, currently 5%.
Separate identity from request content
The private ticket flow splits the systems that know your account, handle plaintext, and hold provider credentials.
Route inside a privacy boundary
The /auto router filters to eligible privacy levels first, then selects for capability, quality, and cost.
See what every route guarantees
Anonymous, Private, TEE, and E2EE labels make the actual privacy boundary visible before a request is sent.
Upstream provider policy still matters on both services. A no-log router cannot make every model provider private. Review the exact route label, and use an explicitly supported E2EE route when you need the strongest available boundary.
