Worth following for the evaluation side of Anthropic’s alignment program, especially where model-written tests are used to surface new behaviors quickly.
4 sources
A good person to follow if you care about the practical evaluation layer at Anthropic rather than only its highest-level alignment claims.
4 sources
A useful profile for the segment of Anthropic that turns alignment concerns into concrete evals, behavior probes, and red-team-style measurement.
4 sources
A useful page for Anthropic’s evaluation stack, especially where new model behaviors are surfaced through generated tests rather than only hand-authored benchmarks.

Important because he is right at the center of the model-written-evals line, which became one of Anthropic’s clearest attempts to discover behaviors faster than manual evaluation can.
