Anthropic Fellows research demonstrated that Claude can research, design, and execute alignment training on other models given just 48 hours and a single GPU. It systematically resolved 10 alignment failure modes without capability regression. Methods generalized to models 4.7x larger, and Sonnet 5 post-trained an early Opus 4.8 checkpoint to near-production safety benchmarks.
Key Takeaways
- βAutomated alignment pipelines resolved 10 failure modes with zero general capability regression.
- βSonnet 5 successfully post-trained an early Opus 4.8 checkpoint to near-production safety metrics.
- βThe full autonomous alignment research setup is open-sourced for external verification.
