Anthropic shows AI improving AI alignment, beating human research directions

kimmonismus · x · 2026-08-29

Anthropic released a paper demonstrating a workflow close to recursive self-improvement, where Claude improved the alignment of other AI models. The AI autonomously searched literature, proposed methods, created training data, trained models, and evaluated results. It fixed all 10 tested alignment failures without degrading general capabilities and even used a weaker Sonnet 5 to align an early Opus 4.8 checkpoint to near-production levels in 60 hours. Results show AI-guided research directions outperform experienced human proposals on average within six hours. While the improved model did not yet become the next researcher to close the loop, most components are now in place.
