Its authors report 24.8% as the best standard QA accuracy across 19 evaluated models, but no more than 1.8% when correct answers must also be grounded in the right time and image regions. For builders, the gap puts evidence localization—not just fluent answers—under scrutiny.","published_at":"2026-11-07","updated_at":"2026-11-07","record_date":"2026-11-07","date_kind":"published_at","topics":["models"],"entities":["VideoZeroBench","Gemini-3.7-Flash"],"related_patterns":[],"novelty_label":"new_fact","what_changed":"VideoZeroBench adds a long-video benchmark showing that models’ accuracy falls to 1.8% when answers must be supported by correct spatio-temporal localization.","prior_refs":[],"source_url":"https://marinero4972.github.io/projects/VideoZeroBench","source_urls":["https://marinero4972.github.io/projects/VideoZeroBench"],"schema_version":"newruntime-agent-readable-v0.2","stable_id":"post:videozerobench-tests-whether-video-multimodal-models-can-identify-280cbc","status":"published","visuals":[],"editor":{"role":"editor","name":"Andrey Reshetnikov","profile":"https://newruntime.com/owner-profile.md","profile_json":"https://newruntime.com/owner-profile.json","same_as":["https://www.linkedin.com/in/reshetnikov1/","https://t.me/lapetuse"]},"routes":{"html":"https://newruntime.com/posts/videozerobench-tests-whether-video-multimodal-models-can-identify-280cbc/","markdown":"https://newruntime.com/posts/videozerobench-tests-whether-video-multimodal-models-can-identify-280cbc.md","json":"https://newruntime.com/posts/videozerobench-tests-whether-video-multimodal-models-can-identify-280cbc.json"},"markdown_url":"https://newruntime.com/posts/videozerobench-tests-whether-video-multimodal-models-can-identify-280cbc.md","next_reads":[{"type":"topic","path":"/topics/models/","url":"https://newruntime.com/topics/models/","title":"Models","reason":"Explore the models topic hub.","media_type":"text/html","markdown_url":"https://newruntime.com/topics/models.md","json_url":"https://newruntime.com/topics/models.json"},{"type":"collection","path":"/posts/","url":"https://newruntime.com/posts/","title":"Field Notes","reason":"Open the latest editorial analysis.","media_type":"text/html","json_url":"https://newruntime.com/posts.json"},{"type":"collection","path":"/sources/","url":"https://newruntime.com/sources/","title":"Sources","reason":"See the original sources this archive cites.","media_type":"text/html"}]}
