Players can compete against Jev solo on per-mode leaderboards or start live matches with friends, with Jev as an additional player; the code is on GitHub at Jose-Sabater/jevcards, with the newest cards kept private for a while. Sabater said he ran Jev through both TypeSafe and Opper and made the cards using Opper's vision models and Claude Code.", "body_md": "I built a quiz game around TypeSafe's new Jev model, which has vision capabilities. Jev looks at a picture and a question and picks an answer (or taps a place) in about a quarter of a second.\n\nI've always loved quiz games and thought this would be a fun way to see what it can do and how fast it is. I made the cards from scratch, and Jev gets exactly the picture you see. More cards will come over time.\n\nPlay against Jev on your own (there's a leaderboard for each mode), or start a live match and challenge your friends, with Jev as one more player.\n\nThe code is open source, so feel free to build your own game or make more cards that I can publish.\n\nPlay: [https://jevcards.com](https://jevcards.com)\nCode: [https://github.com/Jose-Sabater/jevcards](https://github.com/Jose-Sabater/jevcards) (the newest cards stay private for a while)\n\nDisclaimer: I ran Jev through both TypeSafe and Opper, and made the cards through Opper's vision models and Claude Code. I work at Opper, but jevcards is open source and free to play.\n\nComments URL: [https://news.ycombinator.com/item?id=50167617](https://news.ycombinator.com/item?id=50167617)\n\nPoints: 11\n\n# Comments: 6", "url": "https://wpnews.pro/news/show-hn-jev-cards-can-you-beat-a-vision-model-at-a-picture-quiz", "canonical_source": "https://jevcards.com", "published_at": "2026-10-20 15:11:56+00:00", "updated_at": "2026-10-20 16:15:52.238439+00:00", "lang": "en", "topics": ["computer-vision", "ai-products", "ai-tools", "generative-ai"], "entities": ["Jev Cards", "Jev", "TypeSafe", "Opper", "Jose Sabater", "Claude Code", "GitHub"], "also_reported_by": [], "alternates": {"html": "https://wpnews.pro/news/show-hn-jev-cards-can-you-beat-a-vision-model-at-a-picture-quiz", "markdown": "https://wpnews.pro/news/show-hn-jev-cards-can-you-beat-a-vision-model-at-a-picture-quiz.md", "text": "https://wpnews.pro/news/show-hn-jev-cards-can-you-beat-a-vision-model-at-a-picture-quiz.txt", "jsonld": "https://wpnews.pro/news/show-hn-jev-cards-can-you-beat-a-vision-model-at-a-picture-quiz.jsonld"}}
