2.2 Tülu 3 Evaluation

  1. Why does Tülu 3 Eval have separate development and unseen splits?
    The team chose data and methods using only the development evaluations and never looked at the unseen ones during development, so the unseen split measures how much those decisions overfit. They did overfit somewhat, e.g. to IFEval’s specific constraint types.
