An embedded evaluator is an outside safety reviewer given ongoing, employee-like access inside an AI company — desks, badges, laptops, and a contractual right to publish findings — instead of a one-time audit before a model ships. explainx.ai breaks down how the model works, why it's different from red-teaming, and who has actually adopted it.

Joe Benton, who led a safety research team at Anthropic, and Josh Engels, an AI safety researcher at Google DeepMind, both resigned within days of each other in September 2026, telling NBC News "there are no adults in the room."
