New SAPD method trains LLM agents from offline data without environment interaction

Researchers have developed a new method called Step-Advantage Policy Distillation (SAPD) to train Large Language Model (LLM) agents more efficiently using existing offline data. This approach allows agents to learn from past interactions without needing to revisit the environments, thus avoiding catastrophic forgetting often seen with supervised fine-tuning. SAPD decomposes multi-turn trajectories and uses relative step advantage signals to stabilize training, demonstrating improved performance and faster training times compared to existing methods on benchmarks like ALFWorld and WebShop. AI

IMPACT SAPD could significantly reduce the computational cost and time required for training LLM agents by leveraging existing data more effectively.

    SAPD: Learning from Agent Experience without Environment Interaction

    arXiv:2610.27847v1 Announce Type: new Abstract: Scaling the training of Large Language Model (LLM) agents typically requires a large collection of executable environments, whose construction, maintenance, and operation constrain the expansion of training experience. Existing offl…
