Use Layer2C to Pressure-Test AI Infrastructure Claims
Layer2C helps enterprise technology leaders evaluate where AI infrastructure vendors actually operate — across compute, data, orchestration, runtime, reasoning, and applications — and where the enterprise still owns governance, cost, evidence, and accountability.
This site is for CIOs, CTOs, platform leaders, enterprise architects, and procurement decision makers who need to understand what they are actually buying before they buy it.
What This Helps You Do
Use Layer2C to:
- Compare vendors beyond "AI platform" marketing
- Identify which layers a vendor actually controls versus delegates or cedes
- Understand where authority is Retained, Delegated, Ceded, or Absent
- Find governance gaps before production — not after
- Build sharper RFP and briefing questions grounded in architecture
- See where vendor claims depend on partners, roadmaps, or borrowed judgment
- Map operating model implications before a contract is signed
The Buyer Problem
Every vendor claims to be the AI platform. But enterprise buyers do not buy platforms in the abstract. They inherit operating models, governance boundaries, cost exposure, audit responsibilities, and architectural dependencies.
The question most RFPs fail to ask is not "what does this platform do?" It is:
"If this system needs to change, be audited, be constrained, or be overridden — who has the authority to do it?"
That question connects directly to the Decision Authority Placement Model (DAPM). Every component in a Layer2C assessment is classified: Retained (enterprise controls it), Delegated (a substitutable partner provides it), Ceded (vendor controls it), or Absent (no capability exists). The classification answers the authority question, not the capability question.
A Ceded component can be excellent. A Retained component can be inferior. The classification tells you something the marketing deck does not: when your organization needs to change, audit, or override this capability, can it?
How to Use the Assessments
Start with the comparison page. Get the layer status matrix and DAPM profiles for all vendors side by side before reading any individual assessment.
Review the vendor's DAPM profile. Look at the ratio of Retained to Ceded. High Ceded count at Layer 2C — the reasoning plane — is the most consequential governance risk.
Read the full assessment for your shortlisted vendors. Each layer includes gap analysis, borrowed judgment assessment, and working notes.
Look specifically for borrowed judgment — where a vendor's capability claim depends on a partner's roadmap rather than their own. This is where platform stories overreach.
Convert gap findings into briefing or RFP questions. Layer2C gives you the architectural basis for questions vendors are rarely asked. Use the 4+1 AI Platform RFP Framework to translate Layer2C findings directly into procurement language.
The Layer 2C Governance Test
The most consequential layer for enterprise governance is Layer 2C — the Agentic Infrastructure layer, also called the Reasoning Plane. This is where AI agents and models are orchestrated, constrained, monitored, and held accountable.
A vendor passes the Layer 2C test if its infrastructure can make policy-driven placement decisions — not just route requests, but reason about which model, agent, or resource should handle a task given current policy, cost constraints, compliance requirements, and available evidence.
Most vendors today have routing at Layer 2C but not reasoning. Routing is load balancing. Reasoning is governance. If the vendor you are evaluating cannot demonstrate policy-driven placement with evidence capture and audit trails, you are buying a capable system that is not governable at the infrastructure level.
