Metí a Jev en un chat. 🤖 Para que no tengas que volverte loco/a adivinando cómo probarlo. probalo sin instalar nada y sin registrarte. 👉 Probalo acá: lnkd.in/dhFX5XYY Y si querés armar tu propia versión, el código está abierto: lnkd.in/dXSu6ki3 😉

Another Jev competitor just dropped: CLM-8B from @jackyk02 and the Stanford/NVIDIA team, with open weights under Apache 2.0. They claim it's comparable to Jev with up to 9x faster inference We went from zero options to a new one almost every day!

Seguí con dos consultas: un código de verificación que no llega y cómo navegar con el teclado. Jev eligió seguridad y manual de usuario; Laya, privacidad y términos. En ambos casos me convencen más las elecciones de Jev, aunque Laya volvió a responder más rápido con mi setup.

Empecé a escribir: "¿Qué precio tiene la suscripción anual?". Antes de pulsar Enviar Jev y Laya ya sugerían planes_y_precios.md. Eso es lo que quería probar: si el agente puede tener una pista de qué consultar antes de que le llegue la pregunta, con mi setup Laya fue más velóz

Explorando qué se puede hacer con Jev y Laya, que (los de moda), me pregunté si podrían ayudar a un agente de soporte a preparar el contexto mientras el usuario escribe su mensaje. El contexto es clave para un LLM, así que armé una startup ficticia con 7 documentos. 🧵

Jev vs Laya-MLX isn't really a rivalry. Jev is the original, commercial model. Laya-MLX is a local, open-source take on the same idea, running natively on your Mac. Same core concept: "System One" models. No chatting, no text generation. Just fast, typed decisions. #Jev #Laya

Jev 发布才 8 天,开源替身已经一堆了,今天诺基亚也来蹭热闹了😅 我在 MacBook 上,让官方 Jev 和 3 个开源方案同跑 20 张中文工单🫱 Laya 25ms,比 Jev 快 50 倍 djev 509ms 官方 Jev 1.3 秒 AnyJev 将近 4 秒 仓库都在这: Laya(Mac 版)http://github.com/mizorewww/laya-mlx djev(Mac 版)http://github.com/jamescorbett/mlx-vlm AnyJev http://github.com/nokia-applied-research/AnyJev 但快的,不一定对 👇

Jev is all over my timeline rn 👀 Went looking into it and stumbled across Laya. Open-source System 1 decision model. They even have a Jev comparison 👀 7.8× faster. 3× better calibrated. 45/51 languages. Self-hosted. And the weights are right there. 😂 Yeah… I am watching this space. https://huggingface.co/convaiinnovations/laya

After seeing Jev everywhere on the feed lately, we had to try this direction ourselves. We’re bringing Laya to Insight O Mate. A fast, open-source, local decision model that fits perfectly with our privacy-first approach to querying NoSQL databases. Your data stays local. Your decisions stay local. Insight O Mate + Laya is coming. Try Insight O Mate at https://insightomate.lunamic.co

啊啊啊啊啊🎉🎉!JEV 黑客松已经出来啦!!! 同时,我也见到了把 Jev 用得最对的一个项目!! Jev 这模型最大的特点: 只会判断,一个字都写不了。所以用它的关键,就是别让它干写字的活。 这个开源的「聊天副驾」就很聪明: 你在微信里收到一句"在吗"或者"方案再想想",它先让 Jev 一秒判出对方真实意图、危险等级 1–9、该马上回还是先晾着; 写回复这活交给另一个会写字的模型起草 3 条,最后再让 Jev 排个序。 判断归判断模型,写字归写字模型。 且它最好的一点:它永远不自动发送。 搞得我都想去闲🐟搞几台吹灰的安卓机啦! 期待后续也能拿下 iOS、macOS、鸿蒙系统! https://x.com/AYi_AInotes/status/2102605821456814286/video/2

Laya just mogged Jev at Tetris. The interesting part isn’t just that a local model won. Laya is an open-weights System One model running locally on a 16GB MacBook Air. Jev, meanwhile, is cloud-based and built with Grok 4.7.

Jev but for images? I built a local model to try it out! 63ms for a 512x384 image and fast enough for 15fps video. Birthday 94%. Golden retriever 78%. Sprinkles 93%. Candles lit 67%. Dog about to eat the cake? 52%.

上次说的 Jev: 不会陪聊,只负责拍板。 这几天又冒出个 Laya。 活差不多,路子不一样。 一起想成: 流水线上专门判题的人, 不写长文,只答「过不过 / 归哪类」。 Jev = 外面请来的裁判 开箱就能用,按量付钱, 选项多、材料长时更稳。 适合懒得自己搭、先要结果的人。 Laya = 自己厨房里养的裁判 权重能下,Apache 开源,本机跑, 更快更省隐私。 但要自己微调;选项一堆时容易糊。 适合有机器、要数据不出门、愿自己调的人。 一句人话: 不是谁取代谁—— 要省事找 Jev,要自己掌控找 Laya。 都是选择题机器,不是聊天搭子

While Jev is down for new invites, I worked with Claude last night to build Vej (a jev clone that runs locally.) It's weakest at score types, but almost 1:1 for noul and choice. You can use it to build and play with jev-based apps until you can get in. github.com/draeder/Vej

congrats on the release! i've included xor on the Decision Index 0.2 benchmark of jev-like models we don't have a vision benchmark yet, but the text-only version got 8th place, strong in arts & human taste x.com/multimodalart/…

Now that I've collected so much data on System One models on my DGX Spark. Lets see if I can beat Jev on size, speed, and accuracy. It will be MIT for anybody to build on. Everything I do on here is open source.

Just trained Tev1 0.8B, a tiny Jev-like classifier. Here it is running completely locally on my mac with @ollama & classifying some tasks. It's extremely fast: only ~50ms E2E latency. Video is not sped up! Releasing weights & benchmarks very soon so you can try it yourself :)
