This is f*cking wild: people built all of this on Jev in five weeks if you have API access and don’t know where to start, copy one of these: jev-ultrafast - a browser agent that picks every click itself and calls a small text model only when it has to type. a Google Flights search from Zürich to London in 7.1 seconds. 23.4k stars https://github.com/browser-use/jev-ultrafast tax-doc-classifier - sorts pages across 261 IRS forms for about $0.001 a page, which the author measures at 34x cheaper and 6x faster than the Sonnet setup it replaced. 505 stars https://github.com/kyotofin/tax-doc-classifier jev-drone - a simulated quadrotor flies a five-station obstacle course from its camera alone, with Jev making a tactical call 2.5 times a second. it got 77.5 m down the course, against 17.7 m without Jev https://github.com/RomanSlack/jev-drone typesafe-chess - chess where every move is a Jev decision. one call per move loses about 170 centipawns a move on average. put a search on top and it drops to 25 https://github.com/TholeG/typesafe-chess pg-jev - a PostgreSQL extension where you filter your own tables in plain English: SELECT * FROM people WHERE jev(people, ‘the name is European’). a 129-row table cost about $0.0009 the first time and 6 ms from cache https://github.com/realZachi/pg-jev jev-curate - streams Parquet and JSONL rows through Jev and keeps only what clears the bar. the README claims 1,500+ rows a second at about $4.20 per 100M tokens https://github.com/AkashPriyadarshii/jev-curate killmyidea - describe your startup idea, Jev scores it on a handful of plain questions and hands back kill it, fix it or ship it https://github.com/monteduro/killmyidea jev-trader - one buy-or-sell decision every ~300 ms block on the Monad order book https://github.com/jarrodwatts/jev-trader jev-doom-agent - real Chocolate Doom compiled to WebAssembly, two engines on the same map, Jev choosing the tactical macro https://github.com/lukaske/jev-doom-agent jev-t-rex-runner - the Chrome dinosaur game, played by Jev picking jump, duck or keep running https://github.com/joshlarsen/jev-t-rex-runner almost none of these write a word. they return a pick, a score or a yes/no against answers someone defined in advance run the three-question test from the article before you build an eleventh
