Independent control assessment gives leading AI labs weak containment grades

Guidelight’s August control assessment, current through 18 August, graded Anthropic and OpenAI C+ (2.50), Google D+ (1.50), xAI D− (0.83) and Meta F (0.67). It scored public evidence for logging, monitor effectiveness, gated actions, circuit breaking, third-party review and containment planning.
Why it matters: The report moves AI control from broad principles to inspectable operating practices, but it relies on public disclosures and is neither a regulator audit nor peer-reviewed research.
Business/technical/strategic impact: Boards can use the six practices as a due-diligence checklist. Scores should prompt evidence requests, not be treated as definitive measures of internal controls.
