A good person to follow for the evaluation-heavy side of Anthropic alignment work, especially where early assistant training later feeds into reasoning-faithfulness and model-written testing.
4 sources
A useful person to follow for the part of Anthropic that moved from assistant training into explicit behavior-discovery and evaluation work.
4 sources
Important because his work sits near the point where technical alignment, evaluation practice, and the public case for safer frontier-model deployment meet.
4 sources
Worth following for the evaluation side of Anthropic’s alignment program, especially where model-written tests are used to surface new behaviors quickly.
