VALID Trust

A framework for qualifying AI suppliers in regulated life sciences. It decomposes any vendor into four pillars based on what the AI actually does in the workflow — then scopes the qualification work to exactly those pillars.

What the AI does decides how you qualify it

Most vendors trigger more than one pillar. A static classifier triggers Probabilistic Acceptance and Continuous Monitoring; an autonomous trial-design agent triggers all four. The framework's job is to make explicit which pillars apply, and to scope the work accordingly — because a single SOC 2 report answers none of them.

Pillar 01

Generative AI Validation

Applies when the AI generates

Whenever the system produces novel content — text, structured records, draft documents — qualification concentrates on where that content comes from and whether it can be trusted and reproduced.

Pillar 02

Agentic AI Governance

Applies when the AI acts

Whenever the system takes autonomous action across multiple steps or tools, qualification concentrates on how far that autonomy reaches and where human oversight is wired in.

Pillar 03

Probabilistic Acceptance

Applies when the AI varies

Whenever outputs vary for identical-looking inputs, qualification concentrates on whether that variance is bounded, calibrated, and quantified rather than left implicit.

Pillar 04

Continuous Monitoring

Applies when the AI can change

Whenever the model, its data, or its operating context can change after deployment, qualification concentrates on how change is detected, versioned, and governed over time.

The decision logic

Five steps from vendor to qualification

The pillars define what to assess. The decision logic defines the order of operations for a real vendor in front of you.

1

Map the vendor to the pillars

Determine which of the four pillars apply, based on what the system actually does. A static classifier triggers two; an LLM authoring tool triggers three; an autonomous agent triggers all four.

2

Run the pillar-specific questions

For each applicable pillar, work through the qualification questions specific to that AI modality. The questions for Generative AI Validation are not the same as those for Agentic AI Governance.

3

Apply the cross-cutting threads

Across all applicable pillars, run the four threads uniformly: security (AI-specific controls beyond ISO 27001), explainability, stakeholder communications, and supplier-qualification meta-questions — certifications, disclosure posture, contractual commitments.

4

Locate the validation-inheritance boundary

Map the supply chain — foundation model → wrapper vendor → hyperscaler → sponsor — and mark exactly where inherited validation ends and your own qualification work must begin.

5

Scope and issue the qualification decisionconfirm wording

Consolidate the pillar findings, thread checks, and inheritance boundary into a scoped qualification decision: qualified, qualified-with-conditions, or not qualified — with the residual obligations that fall to the sponsor named explicitly.

Step 4, in detail

The validation-inheritance boundary

The hardest question in AI supplier qualification is not whether a vendor is trustworthy — it is where someone else's validation stops being yours to rely on. VALID Trust makes that boundary explicit across the supply chain.

Validation does not flow cleanly down this chain. Each handoff is negotiated rather than standardized, and the sponsor inherits only what is explicitly documented and contractually committed — everything else falls back to the sponsor to validate. Locating that line is what turns a vendor relationship into a defensible qualification.

Where this sits in the architecture

VALID Trust is the supplier-qualification control that makes the House of AI Trust defensible — it runs horizontally as one of the four cross-cutting threads rather than living in a single layer. The lifecycle's change-control step and the Error Taxonomy both lean on it when a third-party model is in scope.
