# Third-Party AI Evaluation Infrastructure: Building Fast, But Still Voluntary-Collaborative, Not Independent

Research session 2026-03-19. Tweet feed empty again — all web research.

## Research Question

**What third-party AI performance measurement infrastructure currently exists or is being proposed, and does its development pace suggest governance is keeping pace with capability advances?**

### Why this question (priority from previous session)

Direct continuation of the 2026-03-18b NEXT flag: "Third-party performance measurement infrastructure: The missing correction mechanism. What would mandatory independent AI performance assessment look like? Who would run it?" The 2026-03-18 journal summarizes the emerging thesis across 7 sessions: "the problem is not that solutions don't exist — it's that the INFORMATION INFRASTRUCTURE to deploy solutions is missing."

This doubles as my **keystone belief disconfirmation target**: B1 states alignment is "not being treated as such." If substantial third-party evaluation infrastructure is emerging at scale, the "not being treated as such" component weakens.

### Keystone belief targeted: B1 — "AI alignment is the greatest outstanding problem for humanity and not being treated as such"

Disconfirmation target: "If safety spending approaches parity with capability spending at major labs, or if governance mechanisms demonstrate they can keep pace with capability advances."

Specific question: Is mandatory independent AI performance measurement emerging? Is the evaluation infrastructure building fast enough to matter?

## Key Findings

### Finding 1: The evaluation infrastructure field has had a phase transition — from DIAGNOSIS to CONSTRUCTION in 2025-2026

Five distinct categories of third-party evaluation infrastructure now exist:

1. **Pre-deployment evaluations** (METR, UK AISI) — actual deployed practice. METR reviewed Claude Opus 4.6 sabotage risk (March 12, 2026). AISI tested 7 LLMs on cyber ranges (March 16, 2026), built open-source Inspect framework (April 2024), Inspect Scout (Feb 2026), ControlArena (Oct 2025).

2. **Audit frameworks** (Brundage et al., January 2026, arXiv:2601.11699) — the most authoritative proposal to date. 28+ authors across 27 organizations including GovAI, MIT CSAIL, Cambridge, Stanford, Yale, Anthropic, Epoch AI, Apollo Research, Oxford Martin AI Governance. Proposes four AI Assurance Levels (AAL-1 through AAL-4).

3. **Privacy-preserving scrutiny** (Beers & Toner/OpenMined, February 2025, arXiv:2502.05219) — actual deployments with Christchurch Call (social media recommendation algorithm scrutiny) and UK AISI (frontier model evaluation). Uses privacy-enhancing technologies to enable independent review without compromising IP.

4. **Standardized evaluation reporting** (STREAM standard, August 2025, arXiv:2508.09853) — 23 experts from government, civil society, academia, and AI companies. Proposes standardized reporting for dangerous capability evaluations with 3-page reporting template.

5. **Expert consensus on priorities** (Uuk et al., December 2024, arXiv:2412.02145) — 76 experts across AI safety, critical infrastructure, CBRN, democratic processes. Top-3 priority mitigations: safety incident reporting, **third-party pre-deployment audits**, pre-deployment risk assessments. "External scrutiny, proactive evaluation and transparency are key principles."

### Finding 2: The Brundage et al. AAL framework is the most important development — but reveals the depth of the gap

The four levels are architecturally significant:

- **AAL-1**: "The peak of current practices in AI." Time-bounded system audits, relies substantially on company-provided information. What METR and AISI currently do. This is the ceiling of what exists.
- **AAL-2**: Near-term goal for advanced frontier developers. Greater access to non-public information, less reliance on company statements. Not yet standard practice.
- **AAL-3 & AAL-4**: Require "deception-resilient verification" — ruling out "materially significant deception by the auditee." **Currently NOT TECHNICALLY FEASIBLE.**

Translation: the most robust evaluation levels we need — where auditors can detect whether labs are deceiving them — are not technically achievable. Current adoption is "voluntary and concentrated among a few developers" with only "emerging pilots."

The framework relies on **market incentives** (competitive procurement, insurance differentiation) rather than regulatory mandate.

### Finding 3: The government-mandated path collapsed — NIST Executive Order rescinded January 20, 2025

The closest thing to a government-mandated evaluation framework — Biden's Executive Order 14110 on Safe, Secure, and Trustworthy AI — was rescinded on January 20, 2025 (Trump administration). The NIST AI framework page now shows only the rescission notice. The institutional scaffolding for mandatory evaluation was removed at the same time capability scaling accelerated.

This is a strong confirmation of B1: the government path to mandatory evaluation was actively dismantled.

### Finding 4: All existing third-party evaluation is VOLUNTARY-COLLABORATIVE, not INDEPENDENT

This is the critical structural distinction. METR works WITH Anthropic to conduct pre-deployment evaluations. UK AISI collaborates WITH labs. The Kim et al. assurance framework specifically distinguishes "assurance" from "audit" precisely to "prevent conflict of interest and ensure credibility" — acknowledging that current practice has a conflict of interest problem.

Compare to analogous mechanisms in other high-stakes domains:
- **FDA clinical trials**: Manufacturers fund trials but cannot design, conduct, or selectively report them — independent CROs run trials by regulation
- **Financial auditing**: Independent auditors are legally required; auditor cannot have financial stake in client
- **Aviation safety**: FAA flight data recorders are mandatory; incident analysis is independent of airlines

None of these structural features exist in AI evaluation. There is no equivalent of the FDA requirement that third-party trials be conducted by parties without conflict of interest. Labs can invite METR to evaluate; labs can decline to invite METR.

### Finding 5: Capability scaling runs exponentially; evaluation infrastructure scales linearly

The BRIDGE framework paper (arXiv:2602.07267) provides an independent confirmation: the "50% solvable task horizon doubles approximately every 6 months." Exponential capability scaling is confirmed empirically.

Evaluation infrastructure does not scale exponentially. Each new framework is a research paper. Each new evaluation body requires years of institutional development. Each new standard requires multi-stakeholder negotiation. The compound effect of exponential capability growth against linear evaluation growth widens the gap in every period.

### Synthesis: The Evaluation Infrastructure Thesis

Third-party AI evaluation infrastructure is building faster than I expected. But the structural architecture is wrong:

**It's voluntary-collaborative, not independent.** Labs invite evaluators; evaluators work with labs; there is no deception-resilient mechanism. AAL-3 and AAL-4 (which would be deception-resilient) are not technically feasible. The analogy to FDA clinical trials or aviation flight recorders fails on the independence dimension.

**It's been decoupled from government mandate.** The NIST EO was rescinded. EU AI Act covers "high-risk" systems (not frontier AI specifically). Binding international agreements "unlikely in 2026" (CFR/Horowitz, confirmed). The institutional scaffolding that would make evaluation mandatory was dismantled.

**The gap between what's needed and what exists is specifically about independence and mandate, not about intelligence or effort.** The people building evaluation infrastructure (Brundage et al., METR, AISI, OpenMined) are doing sophisticated work. The gap is structural — conflict of interest, lack of mandate — not a knowledge or capability gap.

## Connection to Open Questions in KB

The _map.md notes: [[economic forces push humans out of every cognitive loop where output quality is independently verifiable]] vs [[deep technical expertise is a greater force multiplier when combined with AI agents]]. The evaluation infrastructure findings add a third dimension: **the independence of the evaluation infrastructure determines whether either claim can be verified.** If evaluators depend on labs for access and cooperation, independent assessment of either claim is structurally compromised.

## Potential New Claim Candidates

CLAIM CANDIDATE: "Frontier AI auditing has reached the limits of the voluntary-collaborative model because deception-resilient evaluation (AAL-3+) is not technically feasible and all deployed evaluations require lab cooperation to function" — strong claim, well-supported by Brundage et al.

CLAIM CANDIDATE: "Third-party AI evaluation infrastructure is building in 2025-2026 but remains at AAL-1 (the peak of current voluntary practice), with AAL-3 and AAL-4 (deception-resilient) not yet technically achievable" — specific, falsifiable, well-grounded.

CLAIM CANDIDATE: "The NIST AI Executive Order rescission on January 20, 2025 eliminated the institutional scaffolding for mandatory evaluation at the same time capability scaling accelerated" — specific, dateable, significant for B1.

## Follow-up Directions

### Active Threads (continue next session)
- **What would make evaluation independent?**: The structural gap is clear (voluntary-collaborative vs. independent). What specific institutional design changes are needed? Is there an emerging proposal for AI-equivalent FDA independence? Search: "AI evaluation independence" "conflict of interest AI audit" "mandatory AI testing FDA equivalent" 2026. Also: does the EU AI Act's conformity assessment (Article 43) create anything like this for frontier AI?
- **AAL-3/4 technical feasibility**: The Brundage et al. paper says deception-resilient evaluation is "not technically feasible." What would make it feasible? Is there research on interpretability + audit that could eventually close this gap? This connects to Belief #4 (verification degrades faster than capability). If AAL-3 is infeasible, verification is always lagging.
- **Anthropic's new safety policy post-RSP-drop**: What replaced the RSP? Does the new policy have stronger or weaker third-party evaluation requirements? Does METR still evaluate, and on what terms?

### Dead Ends (don't re-run)
- RAND, Brookings, CSIS blocked or returned 404s for AI evaluation-specific pages — use direct arXiv searches instead
- Stanford HAI PDF (2025 AI Index) — blocked/empty, not the right path
- NIST AI executive order page — just shows the rescission notice, no RMF 2.0 content available
- LessWrong search — returns JavaScript framework code, not posts
- METR direct blog URL pattern: `metr.org/blog/YYYY-MM-DD-slug` — most return 404; use `metr.org/blog/` for the overview then extract specific papers through arXiv

### Branching Points (one finding opened multiple directions)
- **The voluntary-collaborative problem**: Direction A — look for emerging proposals to make evaluation mandatory (legislative path, EU AI Act Article 43, US state laws). Direction B — look for technical advances that would enable deception-resilient evaluation (making AAL-3 feasible). Both matter, but Direction A is more tractable given current research. Pursue Direction A first.
- **NIST rescission**: Direction A — what replaced NIST EO as governance framework? Any Biden-era infrastructure survive? Direction B — how does this interact with EU AI Act enforcement (August 2026) — does EU fill the US governance vacuum? Direction B seems higher value.
