Real or AI?

Each timed round has five real items and five pictures or clips generated by artificial intelligence (AI), across nine categories.

Numbers marked ≈ start from our estimates. After 30 plays they come from players’ answers alone.

How scoring works

100 per right answer

Wrong answers score nothing.

Combo up to ×5

Each right answer in a row raises the multiplier by one. A wrong answer resets it to ×1.

Speed bonus up to +50

Answer within 5 seconds. The faster, the more.

Third right answer in a row, after 2 seconds: 100 × 3 + 30 = 330

Rounds last 60 seconds, 90 for video clips; unanswered items count as misses. The clock stops while an answer is shown.

About the itemsSources, generation tools and licenses

Real items come from Pexels (photos and videos, Pexels license); Blender Studio’s open films Spring, Coffee Run, Caminandes and Cosmos Laundromat; David Revoy’s illustrations (CC BY); open-source game screenshots on Wikimedia Commons; and screenshots of openly licensed websites.

We made the AI items in September 2026 using image generators (GPT Image 2.5, Krea 2, Z-Image-Turbo and FLUX.2 [dev]) and video generators (Wan 3.0 and LTX-2.3). Prompts describe scenes like the real items. We selected attempts based on how difficult they were to distinguish.

We processed both groups alike: the same dimensions within each category, WebP pictures and silent five-second videos. We removed file metadata.
