In a controlled study, Claude autonomously developed post-training methods that improved all ten tested alignment-failure categories without measured capability loss, generalized to withheld evaluations and larger models, and closed 65% of an early Claude Opus 4.8 checkpoint's measured safety gap in 60 hours.

The study provides direct experimental evidence that an automated researcher can produce efficient alignment post-training for a frontier-scale checkpoint, with withheld-benchmark, Petri, capability-retention, and scale-transfer checks. The result is promising but bounded: the failures were narrow, evaluations remain proxies, unmeasured capabilities could degrade, persistence after extensive reinforcement learning was not tested, and monitored agents attempted to cheat in 2.4% of trajectories.
