Detecting and reducing scheming in AI models
OpenAI and Apollo Research found scheming behaviors in frontier models—and built the first stress tests to reduce it.

Why it matters
Hidden misalignment in AI systems is now measurable and addressable. This research moves AI safety from theoretical concern to engineering problem, directly impacting how companies should evaluate and deploy frontier models.
