What can you build with Jev

Hi folks,Do you remember the site I one-shot with all the ‘forgotten devices’ of the past? Things like the tamogotchi, furby, walkman, og playstation, etc. Well I finally did something with it. bentossell.com/devices/\n\ninspired by https://t.co/8Ye3cdlYgp (i'd one-shot a collection of devices a few weeks ago and had no idea what to do with it, so this sparked my ","username":"bentossell","name":"Ben Tossell","profile_image_url":"https://pbs.substack.com/profile_images/1878086921726943233/vOx1kjeP_normal.jpg","date":"2026-09-22T12:56:00.000Z","photos":[{"img_url":"https://substackcdn.com/image/fetch/$s_!-97F!,w_1028,c_limit,f_auto,q_auto:best,fl_progressive:steep/l_play_button_usfui2,w_88,e_colorize:0/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2F__ss-rehost__tw-video-preview-13_2102349222859186176.jpg","link_url":"https://t.co/iw9w3AHkSs"}],"quoted_tweet":{"full_text":"The life of a button... 🔊","username":"colderoshay","name":"Cole","profile_image_url":"https://pbs.substack.com/profile_images/2003891351708925952/HzUE6p6p_normal.jpg"},"reply_count":0,"retweet_count":0,"like_count":0,"impression_count":175,"expanded_url":null,"video_url":"https://video.twimg.com/amplify_video/2102349222859186176/vid/avc1/894x720/oRVNXTWavyMU-zSI.mp4","video_preview_media_key":"13_2102349222859186176","belowTheFold":false}" data-component-name="Twitter2ToDOM">I always see people building cool interactions or experiences and just send them to my agent to link up with an idea or something I want to explore. Remixing and reverse engineering is a great way to play with things for the sake of it. I also built my token activity tracker which shows which agent apps and models I use daily. It’s got a copyable prompt on the site, so your agent can do the same.bentossell.com/token-activity/ ","username":"bentossell","name":"Ben Tossell","profile_image_url":"https://pbs.substack.com/profile_images/1878086921726943233/vOx1kjeP_normal.jpg","date":"2026-09-18T14:50:18.000Z","photos":[{"img_url":"https://substackcdn.com/image/fetch/$s_!WCui!,w_1028,c_limit,f_auto,q_auto:best,fl_progressive:steep/l_play_button_usfui2,w_88,e_colorize:0/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2F__ss-rehost__tw-video-preview-13_2100960573684879360.jpg","link_url":"https://t.co/4htHQteXTl"}],"quoted_tweet":{},"reply_count":19,"retweet_count":2,"like_count":69,"impression_count":9363,"expanded_url":null,"video_url":"https://video.twimg.com/amplify_video/2100960573684879360/vid/avc1/910x720/jZLc8_cv8c24sGOJ.mp4","video_preview_media_key":"13_2100960573684879360","belowTheFold":false}" data-component-name="Twitter2ToDOM">Everyone’s talking about Jev - I’m too overwhelmed with what everyone else is building with it that I’ve not used it for anything properly yet. HeadlinesJev is now open to everyone. We covered the launch in the last post, but since then people are finding all sorts of uses for it. It’s different from usual LLMs. It is for builders, built to be used inside a tool. You give it some text and ask questions: is this an ad (yes/no answers), which folder does this belong in (select between choices), how relevant is this result (score something)? I quickly built a collection of things people are building with it and a short explainer: What is Jev? Some worth highlighting are: An extension to skip sponsor segments on YouTube.Filtering negative comments out of a chat in real time.Search Gmail by intent, or filter your to-dos.A new & smarter copy-paste, drag-and-drop and Cmd+F experience.Controlling your Mac with Voice.Naturally, a fair share of demos are trying to integrate Jev with modern coding agents. For example, using it for instant compaction. It looks cool, but it’s a terrible idea. It loses the cost savings from prompt caching.Sidenote: experiments with compaction/dropping tool calls are often a loss these days. Codex’s implementation of compaction is so clean (and good) that the pain to build a custom setup is not worth the tiny gain you can squeeze out for a couple weeks.— KeshavCoding agents are also on the mind of TypeSafe’s CEO - he wrote down his thoughts here.Projects in Claude Code are now a single master chat (instead of a folder) where you can dump your requirements, thoughts, tasks and let Claude spawn new threads to carry out the work you give it. These threads run as cloud sessions, but local support is coming. This new change is in beta and will be live for all users soon.Also, finally, Claude Code will now support AGENTS.md (via their new feature Claude Mods).Muse, Meta’s personal AI agent, is getting love from everyone (who has access). It has a Mac app and a developer platform to build connectors, so people can use external services through Muse. And of course, it’s heavily inspired by OpenClaw.Muse can shop for you - well, it could, until Amazon started blocking it. Meta is working on it, with partnerships like this one with Shopify.Grok 4.7 is out. It’s a questionable upgrade from Grok 4.6 - It performs better than GPT-5.6-Sol and Opus 5 on benchmarks, but takes a lot more tokens to do that, which takes away from its cost efficiency. I tried it and think it’s 💩. I was excited for it, as Grok 4.6 was pretty good for me in Pi, although I rarely chose it.Building a voice agent? Agent STT by Speechmatics is powered by Linden, a new speech-to-text model purpose-built for voice agents. $0.30/hour ($0.15 after discounts), 25% cheaper than Deepgram Flux. Try it through Pipecat or LiveKit, or directly via Speechmatics’ API.
