Methodology

Letter-grade ratings of frontier AI labs across six safety domains: risk assessment, current harms, safety frameworks, existential safety, governance, and information sharing.

Source ↗Methodology ↗License: fair-use-citationStatus: active

Evidence collected up until November 8, 2025. Survey responses submitted by Anthropic, OpenAI, Google DeepMind, xAI, and Z.ai. Meta, DeepSeek, and Alibaba Cloud did not submit survey responses. The 'Survey Responses' dimension is not a scored domain but tracks participation.

Grades are mirrored from upstream sources. We do not score organizations ourselves — see the source link for full methodology and per-indicator detail. Citation of published grades is consistent with fair-use attribution.
