JOLT trains the teacher too, with penalties when its predictions diverge from the student

Perplexity explains JOLT's design: in standard self-distillation only the student trains, so the teacher can exploit shortcuts via privileged information. JOLT instead also trains the teacher on outcome rewards from its own attempts, adding a penalty when its predictions diverge from the student's — ensuring the feedback is usable by the student.
