Stronger teachers don't always yield better students in VLM distillation

A new arXiv paper challenges the conventional wisdom that larger, more capable "teacher" models consistently produce better "student" models in knowledge distillation for vision-language tasks. Researchers found that existing distillation frameworks often fail to scale effectively with larger teachers, leading to degraded performance in downstream applications like visual question answering. This suggests a need for new approaches to designing parameter-efficient multimodal models. AI

IMPACT Challenges assumptions in knowledge distillation, potentially leading to more efficient multimodal model design.

    When Better Teachers Don't Make Better Students: Revisiting Knowledge Distillation for CLIP Models in VQA

    arXiv:2511.17886v2 Announce Type: replace-cross Abstract: Vision-language models (VLMs) have achieved remarkable success across multimodal tasks, yet their substantial computational demands hinder efficient deployment. Knowledge distillation (KD) has emerged as a powerful approac…
