Does Reinforcement Fine-Tuning Improve Generalization of LLM Agents? An Empirical Study
ICML 2026poster
Reinforcement fine-tuning (RFT) has shown promise for training LLM agents to perform multi-turn decision-making based on environment feedback. However, most existing evaluations remain largely in-domain—training and testing are conducted in the same environment or even on the same tasks. In real-wor…
