Twelve-axis governance scoring

Each axis is scored Yes / Partial / No / N/A against public evidence — vendor trust portals, BAAs/DPAs, SOC 2 report cover pages, published methodology documents. N/A applies when the axis is structurally inapplicable (foundation models, for example, defer Section 1557 to the downstream healthcare deployer).

Trust-center maturity

4/ 5

Active trust portal at trust.openai.com — audit reports under NDA, security whitepaper, public policy documents. Falls short of a 5 because no public ISO 42001 or Colorado AI Act statement yet.

Deep dive

Overview

OpenAI is the highest-volume US AI vendor in regulated buyer pipelines. The governance posture is strong on the enterprise tier (BAA, no-train default, US data residency, SOC 2 + ISO 27k stack) and weak on consumer (no BAA, manual opt-out, no residency control). The single biggest deployment risk we see is staff using consumer ChatGPT for work where Enterprise was assumed.

Strengths

  • BAA available for ChatGPT Enterprise + API
  • Default no-train on customer data at Enterprise/Team/API tiers
  • Mature trust portal with under-NDA audit reports
  • US data residency option for enterprise customers

Weaknesses

  • No BAA on Plus/Team/Free — common shadow-AI source
  • No ISO/IEC 42001 attestation as of May 2026
  • No public Colorado AI Act compliance statement
  • Sector-specific readiness (Section 1557, SR 11-7, ABA Op 512) is deployer responsibility — no vendor-side support

Best-fit use case

Regulated organizations that have already standardized on ChatGPT Enterprise with the BAA in place, training opt-out enforced, and Data Residency in the US enabled — and have eliminated shadow consumer-tier use through DLP + identity policy.

Avoid when

PHI workflows on ChatGPT Plus, Team, or Free; clinical decision support without a separately validated Section 1557 layer; bank credit decisioning without an SR 11-7 wrapper on top.

Operator's take

Deploy OpenAI ChatGPT & API when regulated organizations that have already standardized on ChatGPT Enterprise with the BAA in place, training opt-out enforced, and Data Residency in the US enabled — and have eliminated shadow consumer-tier use through DLP + identity policy. The composite score of 53 (grade D) reflects a mixed posture for regulated US workloads. Skip the vendor when pHI workflows on ChatGPT Plus, Team, or Free; clinical decision support without a separately validated Section 1557 layer; bank credit decisioning without an SR 11-7 wrapper on top. In every deployment, treat the cells above as a snapshot — the acquisition that gets to production safely is the one that re-verifies the trust-center posture before contract signature and rebuilds the matrix at renewal.

How this scoring is computed

The composite score blends eleven scoreable axes (BAA, training opt-out, US data residency, SOC 2, ISO/IEC 42001, NIST AI RMF, Colorado AI Act, Section 1557, SR 11-7, ABA Op 512, subprocessor transparency) with the trust-center maturity score. Axes marked N/A are excluded from the denominator so vendors are not penalized for sector-inapplicable axes. The vendor's primary sector amplifies the most relevant axes — healthcare vendors weight Section 1557 ×2, legal vendors weight ABA Op 512 ×2, banking vendors weight SR 11-7 ×2 — so the composite reflects what matters in the actual buying context.

Disagree with this scoring?

EFROS publishes scoring rationale per cell with a public source. If you have evidence that a specific axis should score differently — a new BAA, a new certification, a documented policy change — submit a formal challenge below. We re-score and publish the result with the next quarterly edition (or as a mid-quarter changelog entry if the change is material).

Disagree with a score?

Every cell in the EFROS Index is source-cited. If you have a public source that contradicts a score for OpenAI ChatGPT & API, submit a formal challenge — we re-verify against the source and respond within 14 days.
