New Anthropic research shows Claude aligning Claude all by itself.

And here the model being corrected was more capable than the model correcting it

Looks like another great research at the frontier of recursive self-improvement. AI is reaching the point where it can do much of the research required to make its own stronger successors safer.

The loop it describes closes on itself: propose, train, score, repeat, no researcher required.

Claude autonomously discovered safety-training methods that outperformed one-shot ideas from 28 experienced researchers.

Five agents worked in parallel for up to 48 hours, sharing results while hidden tests and capability gates screened out overfitting and obvious regressions.
