TurnOPD: Making On-Policy Distillation Turn-Aware for Efficient Long-Horizon Agent Training
agentic
What happened
TurnOPD addresses the high cost and inefficiencies of training long-horizon agents via on-policy distillation. Instead of full-horizon rollouts, it introduces a turn-level budgeting strategy that dynamically allocates training resources to critical turns, preventing shallow token concentration and reducing compute overhead.
Why it matters
It makes training long-horizon agents significantly cheaper and faster by focusing compute on critical decision points.
The take
Long-horizon agent training is notoriously expensive because of the combinatorial explosion of trajectories. Turn-level budgeting is a highly practical optimization that makes training custom, agentic models much more viable for teams without infinite compute.
Do this
Read the paper to implement turn-aware budgeting if you are training or fine-tuning LLMs for multi-turn, long-horizon agent tasks.
