Decomposed On-Policy Distillation for Vision-Language Reasoning: Steering Gradients for Visual Grounding
arXiv:2606.00564v1 Announce Type: cross Abstract: While on-policy distillation offers dense supervision for training small reasoning models, its optimization dynamics in the multimodal domain remain under-explored. In this work, we challenge the standard monolithic view of Vision-Language Model (VLM) distillation by mathematically decomposing the loss into two distinct components: the language prior and visual grounding. Our analysis uncovers that gradient vectors for these components are nearly orthogonal, indicating that the objective of aligning with the teacher's language distribution is g
The paper tackles a core challenge in multimodal AI, on-policy distillation for Vision-Language Models, by proposing a new decomposed approach for optimizing smaller, more efficient reasoning models.
This research provides a fundamental architectural insight into improving VLM efficiency, potentially accelerating the development and deployment of capable AI systems in resource-constrained environments.
The understanding of VLM distillation optimization shifts from a monolithic approach to a decomposed one, allowing for more targeted and efficient training of smaller models.
