# Stanford 2026: Responsible AI Safety, Fairness Gap Widening

> Stanford's 2026 AI Index turns its attention to responsible AI and finds that our ability to measure safety and fairness is falling behind how fast the models themselves are improving. The most eye-catching figure is hallucination, across 26 top models the rate at which they confidently make things up ranges from 22 percent all the way to 94 percent, a spread so wide it undercuts any simple claim that the technology is uniformly reliable. The transparency picture is going the wrong way too. The Foundation Model Transparency Index dropped from 58 in 2024 to 40 in 2025, meaning the public knows less about how leading models are trained and tested even as they get more powerful. One bright spot, the share of organizations with no responsible-AI policy at all fell sharply. The report's real contribution is insisting on numbers where the industry prefers vibes. It is easy to say a model is safe or fair, harder to show it, and Stanford's data makes the gaps visible. For policymakers writing rules and companies deploying these systems, that measurement gap is not an academic footnote, it is the whole problem.
