TimeScope: How Long Can Your Video Large Multimodal Model Go?

What changed

TimeScope is an open-source benchmark designed to measure how well vision-language models understand long videos. By adding short “needle” clips into videos ranging from 1 minute to 8 hours, it evaluates three skills: - localized retrieval, - information synthesis, - fine-grained temporal perception. To address this, we're excited to introduce TimeScope, a new open-source benchmark hosted on Hugging Face.

Why it matters

A concrete addition to Practical AI: Tools, Models & Frameworks: it changes what's available to builders today rather than being general commentary.
