xAI, OpenAI, and Anthropic cosign AEF-1 evaluator standard

A new standard called AEF-1 has emerged for third-party AI evaluators, with xAI, OpenAI, and Anthropic all cosigning it.

Why it matters: A shared standard for independent evaluation is a concrete step toward external accountability for frontier AI systems, rather than labs grading their own homework. It complements recent moves like Amodei's call for AI oversight and the broader industry debate over development pacing and safety governance.
