Less Is More, but Where? Dynamic Token Compression via LLM-Guided Keyframe Prior

arXiv — cs.LGTuesday, December 9, 2025 at 5:00:00 AM
  • Recent advancements in Video Large Language Models (VLLMs) have led to the introduction of Dynamic Token compression via LLM-guided Keyframe prior (DyToK), a method that enhances efficiency by dynamically adjusting token retention ratios based on semantically rich frames. This approach addresses the computational challenges posed by lengthy visual token sequences in long videos.
  • The development of DyToK is significant as it allows for improved temporal modeling efficiency without the need for extensive training, potentially reducing computational costs and enhancing the performance of VLLMs in video understanding tasks.
  • This innovation aligns with ongoing efforts in the AI field to optimize model efficiency, as seen in various frameworks aimed at enhancing VLLMs and multimodal models. The focus on dynamic token management and pruning techniques reflects a broader trend towards addressing computational bottlenecks in AI, emphasizing the need for more efficient processing methods in handling complex visual data.

SmokeBench: Evaluating Multimodal Large Language Models for Wildfire Smoke Detection
NeutralArtificial Intelligence
A new benchmark named SmokeBench has been introduced to assess the capabilities of multimodal large language models (MLLMs) in detecting and localizing wildfire smoke in images. The benchmark includes four tasks: smoke classification, tile-based and grid-based smoke localization, and smoke detection, evaluating models such as Idefics2, Qwen2.5-VL, and GPT-4o. Results indicate that while some models can identify smoke over large areas, they struggle with precise localization, particularly in early detection stages.
