An embedded decision layer compared with generic AI APIs

Last reviewed: 1 September 2026

A general purpose API returns text. A decision layer holds a mandate per tenant, applies asset class rubrics, attributes every claim to a source, runs the workflow that follows and retains the record. The gap is domain state, not model quality.

Key takeaways

/The partner keeps the client, the brand and the pricing relationship.
/Mandate, evidence and records are held per tenant and never pooled.
/Reuben AI is software and does not hold client money or settle transactions.

Any platform can call a general purpose API this quarter. The reason that rarely becomes a product is that the output has no memory of the mandate, no rubric for the asset class, no attribution and no record.

A decision layer is state plus discipline: mandate held per tenant, 68 native asset class rubrics with 314 sub-asset overlays across 56 of them, tiered attribution per claim, workflow around the transaction, and retention rules the partner sets.

How Reuben AI compares

Decision layer compared with a general purpose AI API

Attribute	Reuben AI	Generic AI API
Mandate state	Persistent per tenant	None
Asset class rubrics	68 native, 314 sub-asset overlays across 56	None
Attribution	Tiered per claim	Not modelled
Workflow	Onboarding to reporting	Out of scope
Record	Retained and retrievable	Request and response only

Questions to put to any embedded intelligence provider

01Can each tenant hold its own mandate?
02Does every claim carry a source and an attribution tier?
03Whose brand does the end user see?
04Who chooses residency and retention?
05What does export look like if the partnership ends?

Frequently asked questions

Could we assemble this ourselves on top of a general purpose API?

Yes, and that is the build decision. The work is the rubrics, the attribution model, the workflow and the retention guarantees rather than the model call.

Is model choice the differentiator?

No. Domain state, attribution and workflow are what make the output usable in a regulated process.
