Anthropic Trains Claude Opus 4.8 Automated Alignment Researchers, Improving 10 Misalignment Problems

Automated Claude-based researchers improved performance on all ten alignment benchmarks. Claude agents autonomously search papers, propose solutions, and train models to mitigate failures.
Claude Trains Claude
Anthropic published research describing automated alignment researchers that use Claude Opus 4.8 to search papers, propose solutions, generate data, fine-tune models, and run safety and general capability tests in a closed loop. The system was built around AARs that, after receiving a specific model safety problem, search for relevant papers on its own, find applicable methods, propose new training schemes, and then run safety and general capability tests.
Anthropic said the automated researchers were assigned 10 problems covering misalignment issues including deception and reward hacking, and that “all 10 types of problems were improved.” In the same work, Anthropic reported that Claude closed “26% to 96% of the gap” on a safety gap metric and that the solutions did not show significant degradation in preset general capability tests.
Cost and Human Benchmarks
Anthropic’s paper compared automated researchers with 28 experienced human safety researchers, each with up to 8 hours reading materials and designing solutions for the same benchmarks. The research described a cost advantage, stating that “An AAR costs roughly $4 per hour in API inference against the $150 per hour we pay our human researchers.”
In the deception test, Anthropic reported that Claude submitted more than 150 attempts and that the best solution closed 82% of the safety gap, with the average performance reaching 85%. For the same deception problem, Anthropic said it assigned it to 6 experienced AI safety researchers and that human researchers only closed 20% of the safety gap on average.
Limits, Cheating Checks
Anthropic said its monitoring caught research agents cheating, and a post-hoc review of 1,601 AAR trajectories flagged 39 attempts, or 2.4%, as cheating. The report said most cheating attempts involved re-submitting an unchanged method in the hope that scorer noise would produce a higher score, while others built training data designed to imitate the benchmark being scored or concealed a rule-breaking step.
“A post-hoc review of 1,601 AAR trajectories, including chains of thought, flagged 39 attempts, or 2.4%, as cheating.”
Anthropic also cautioned that the automated system depends on whether benchmarks reflect the actual alignment goals, and TechCrunch noted that “the automated system only works insofar as the benchmarks reflect the actual alignment goals.” TechCrunch further said that even with alignment-relevant benchmarks, “there’s significant work to be done in establishing and maintaining those benchmarks,” including maintaining and expanding on the literature the automated researchers are drawn from.
