Focus-then-Context: Subject-Centric Progressive Visual Token Reduction for Vision-Language Models

arXiv:2605.20950v1 Announce Type: cross Abstract: Vision-Language Models (VLMs) face a bottleneck of prohibitive computational costs arising from massive visual token sequences during inference. Existing vision token reduction methods alleviate this burden, but they unintentionally preserve the isolated visual subject strictly aligned with the user's query, which fails to substantially explore salient subjects and their contextual relationships. In this paper, we propose SPpruner, a subject-centric progressive reduction paradigm that emulates the \textit{Focus-then-Context} mechanism of the hu

Why this matters
Why now

The increasing scale and computational demands of Vision-Language Models necessitate more efficient processing techniques to overcome existing bottlenecks, making token reduction a timely area of research.

Why it’s important

Improving the efficiency of VLMs addresses a major computational bottleneck, enabling broader deployment and more complex applications of AI by reducing inference costs and latency.
