sjgadler · x · 2026-08-19
Guidelight AI released its first assessment of AI control practices at frontier companies (Anthropic, Google, Meta, OpenAI, xAI). Based on public materials, the report evaluated six foundational practices: Logging, Monitor efficacy, Gated actions, Circuit breaking, Third-party review, and Containment plan.
Key Findings:
- Widespread Gaps: Basic control practices are, at best, partially implemented across all scored companies.
- Rankings: Anthropic and OpenAI tie for the top grade of C+ (2.50/5), followed by Google (D+, 1.50), xAI (D-, 0.83), and Meta (F, 0.67).
- Specific Deficits: xAI and Meta show near-zero implementation in logging and monitoring efficacy. Most companies lack effective third-party review and containment plans.
