Anthropic's Frontier Safety Roadmap

Christopher WallaceOct 2, 2026

Anthropic set a September 30th deadline, but we've yet to see any announcement of their provable inference prototype. I thought this was interesting because it's a very important part of the AI supply chain that folks aren't tracking, and it could establish responsible training standards. > We will develop a prototype by September 30, 2026 of provable inference, a technique for reliably, provably “signing” AI model outputs in a way that makes them attributable to a specific set of model weights. In the future, it’s possible that very sophisticated attackers will seek to infiltrate our systems and modify our models after we’ve trained them - whether to sabotage our work or co-opt our models into serving their own goals. If we could reliably and systematically verify that model outputs were coming from a specific set of model weights, we believe this threat would be significantly reduced.
