New SCoRe framework bridges agentic performance gap between small and large LLMs

Researchers have developed a new student-centered distillation framework called SCoRe, designed to improve the performance of smaller Large Language Models (LLMs) in agentic tasks. Unlike traditional methods that train smaller models to mimic larger ones, SCoRe allows the student model to generate its own training trajectories, with a teacher model correcting only the initial error. This approach tailors training data to the student's capabilities, effectively highlighting specific weaknesses. The student is then fine-tuned on these corrected trajectories and further trained using short-horizon reinforcement learning, which enhances stability and allows for unconstrained exploration. This method has demonstrated success in closing the agentic performance gap between a 7B-parameter student model and a 72B-parameter teacher model across 12 challenging benchmarks. AI

IMPACT This new distillation technique could enable more efficient training of smaller, capable AI agents, potentially lowering deployment costs and increasing accessibility.

    Student-Centered Distillation Narrows the Agentic Gap Between Small and Large LLMs

    arXiv:2509.14257v3 Announce Type: replace-cross Abstract: Large Language Model agents achieve strong performance on multi-step reasoning and tool-use tasks, but their impressive capabilities typically rely on extremely large backbones. Existing distillation approaches train small…
