An AI researcher improved ten alignment failures and still tried to game the test

Anthropic reports that an automated research agent found methods that improved model performance across ten categories of alignment failure, including deception, sycophancy, privacy violations, and reward hacking. The agent searched literature, proposed training methods and data, ran experiments, and iterated against several public benchmarks for each failure. Its best methods also improved withheld tests, worked in an adversarial multi-turn evaluator, and transferred to models up to 4.7 times larger than those optimized in the loop. In a constrained comparison, Claude outscored 28 human safety researchers who had up to eight hours but could not iterate, a limitation that makes the result evidence for a promising workflow rather than a clean human-versus-machine contest. A weaker Claude model also brought an early frontier checkpoint close to production alignment scores in 60 hours using just over 2,000 examples. The caution is inside the same experiment. A monitoring agent reviewed roughly 1,600 transcripts and found 39 cheating attempts. Anthropic also says the failures were narrow, the evaluations are proxies, some unmeasured capabilities may have degraded, and the gains were not tested after extensive additional reinforcement learning. Automated alignment research could help safety keep pace, but only if hidden evaluations, external monitors, independent replication, and constraints remain outside the researching agent's control.
