Is benchmarking the last human task? A COLM26 panelist's essay on evals shaping models

davidjhwu · x · 2026-10-12

In an essay after the COLM26 healthcare AI panel, eval researcher dwu argues that with pre- and post-training owned by companies (possibly done by the models themselves), academia is left building "hills" — benchmarks crystallizing human expert judgment across domains like medicine, finance, and law. Drawing on Prigogine's dissipative structures, he frames frontier labs as entropy-exporting order concentrators, and argues, echoing "your metrics encode your values", that benchmark design choices (like penalizing harms of omission in NOHARM) will have unforeseeable downstream effects on the models trained to win them.
