Centurian vs Credo AI

[ TL;DR ]

Credo AI is a pure-play AI governance and observability product focused on policy documentation, ethical guardrails, and risk-tier classification. Centurian is the operational control plane that registers, governs, evaluates, attributes cost to, and audits agents on one data spine. Credo lacks Multi-rail Cost, trajectory evaluation, framework marketplace, and runtime Rego enforcement — the four capabilities that turn governance from a quarterly report into a continuous control surface.

Side-by-side

Capability	Credo AI	Centurian
Policy documentation + risk tiering	Yes	Yes
Runtime policy enforcement (deterministic Rego)	No	Yes (Neuro-Symbolic)
Trajectory evaluation engine	No	Yes (Measure product)
Multi-rail Cost (model + MCP + x402 + subs + platform)	No	Yes
Two-sided framework marketplace	No	Yes
Vertical-specific eval libraries	No	Yes (T&L FMCSA + EDI X12)
Bitemporal evidence chain (Ed25519-signed)	Reporting-grade	Court-defensible
PLG free-tier solo developer flow	No	Yes
ISO 42001 / NIST AI RMF reporting	Yes (their core)	Yes (one of many frameworks)

Pure governance vs operational control plane

Pure-LLM governance tools translate plain-English rules into model prompts. The model decides whether to obey. When it hallucinates, the rule silently fails. By the time you find out, the agent has wired the money or exported the PII. Centurian compiles policy into Rego and executes deterministically. The reasoning layer suggests; the symbolic layer enforces. That is the line between an audit trail and a liability.

FAQ

How is Credo AI different from Centurian?

Credo AI is a pure-play AI governance and observability product focused on policy documentation, ethical guardrails, and risk-tier classification. It does not have multi-rail Cost, no two-sided framework marketplace, no trajectory evaluation engine, no x402 stablecoin attribution, and no vertical-specific eval libraries. Centurian is the operational control plane: registration, governance enforcement, trajectory eval, multi-rail cost attribution, and framework distribution all on one data spine.

Does Credo AI enforce policy at runtime?

Credo AI is documentation-led. It maps policies, classifies risk tiers, and supports automated reporting against frameworks like ISO 42001 and NIST AI RMF. Runtime enforcement of agent actions is not its core capability. Centurian uses a Neuro-Symbolic architecture: an LLM compiles plain-English policy into Rego, which executes deterministically in a hardened sandbox. The compiler is gated by a signed test corpus and staged 10% to 100% over 14 days. Once a Rego rule is deployed, the LLM cannot bypass it.

Can Credo AI track AI agent spend?

No. Credo AI's product surface is governance and observability. It has no multi-rail Cost product. Model API spend, MCP tool-call spend, x402 stablecoin spend, SaaS subscription spend, and platform spend (AWS / Azure / GCP) are not unified per-agent. Centurian's Cost product covers all five rails with cost_source attribution non-null on every record.

When should you use Credo AI alongside Centurian?

If you have an existing Credo AI deployment for ISO 42001 / NIST AI RMF policy mapping and risk-tier reporting, Centurian complements it: Centurian runs the operational layer (registration, runtime enforcement, trajectory eval, cost, audit) while Credo AI continues to handle the governance documentation surface. The bitemporal evidence chain Centurian generates can be ingested into Credo AI's reporting via API.

Why has Credo AI not entered Cost or framework marketplace?

Horizontal pure-governance products at <$50M revenue have no commercial reason to broaden into FinOps or build a partner-distributable marketplace. Their next $50M comes from deepening governance, not widening into adjacent categories. Centurian's defensible position is structural: each adjacent product's commercial logic precludes entering the intersection.
