Show HN: Jev Cards, Can you beat a vision model at a picture quiz?

27 points totisjosema 1 hour ago 10 comments

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.

I'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.

Play 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.

The code is open source, so feel free to build your own game or make more cards that I can publish.

Play: https://jevcards.com Code: https://github.com/Jose-Sabater/jevcards (the newest cards stay private for a while)

Disclaimer: 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.

I got a lot of answers wrong (half of them maybe?), and the ones I got it right Jev was still faster.

Play some more you will get the hang of it :) The first 200 cards I did: Jev got 160 right, at a median of 261 ms , so no need to feel bad

Interesting. Jev is certainly faster but it was wrong quite a bit more than I was.

yeah the different games play to different strengths, you can play multiplayer with friends also

Could you add an option to remove musical theory questions? I mean, I know Jev can ace those as well, but I can only click at random, that's unfun

just play again :), but will consider adding whitelist/blacklist of categories

Would prefer if the audio button was at the top right of the page etc.

Will take a look, should already be there during a game though

Very cool demo! Although I feel that incorrect answers should be penalized more. For instance- I got 100% in about 45 seconds on the sprint. Then, I clicked through as fast as I can (only limited by finding the right targets) and got a score of 42s, technically better than my first score but I only got 20% right.

Thanks for the feedback! And now that you showed everyone a cheat sheet we will get many high scores, so lets increase the penalty of wrong answers and reset the leaderboard! Thanks a lot for the insights
