Token-Efficient Long Video Understanding for Multimodal LLMs | Paper explained

AI Coffee Break with Letitia
7,760 views •

Long videos are a nightmare for language models—too many tokens to handle, plus many tokens are redundant, slow inference, and limited context windows. STORM ⛈️ changes that. In this AI Coffee Break, we explain STORM, a new architecture from NVIDIA and collaborators that improves long video understanding using Mamba layers for temporal modeling and token compression. The result? Better accuracy than GPT-4o on key benchmarks and up to 8× more efficiency. AI Coffee Break Merch! 🛍️ https://ai-coffee-break-with-letitia.myspreadshop.de/ ☕ Grab a cup of coffee and learn: • Why current Video LLMs struggle with long sequences • How STORM uses Mamba to inject temporal context before compression • How it reduces visual tokens by a factor of 8—without sacrificing performance • Benchmarks: MVBench, MLVU, and beyond • Why this is a big step toward real-world video comprehension 📃 Jindong Jiang, Xiuyu Li, Zhijian Liu, Muyang Li, Guo Chen, Zhiqi Li, De-An Huang et al.
