Subclaims¶

q2 i? Across evaluated teacher models, teaching sessions typically end within 30 dialogue turns; without an upper bound some models fail to emit the termination token and enter repetitive exchanges. → Zheng Li 2026

q2 · i? · associational · r1

Observational analysis of average dialogue turns per teaching session across teacher models (Figure 2). The authors observed repetitive exchanges such as mutual acknowledgments when no turn bound was set, and set a 30-turn maximum.

"We observe that teaching interactions typically con- clude within 30 turns across models. To prevent potential dead loops between the teacher agent and the student agent, we therefore set the maximum number of dialogue turns to 30."
