The best way to learn something is to build with it! I built Jev Explained with 4 examples that show what Jev is, how its primitives work, and how to use them in practice Clone the repo, open Claude Code or Codex, and ask it to create a new example using the existing codebase a…↗

Introducing a new way FIND (⌘F) with @typesafeai Jev. Find what you mean, not what just matches. Super fast and near real-time. Made it 100% open-source chrome extension.↗

The life of a button... 🔊↗

A TypeScript-based repository providing explanations for Jev ("jev-explained"), likely serving as documentation or learning material to help readers understand the concept.↗

Quite an interesting turn in LLM diversity, if the market starts looking for specialized models that are optimized and branded for different use cases. Should be very good for the market and open more room for non-frontier neolabs!↗

Running Jev to see how fast it can remove negative comments from chat↗

@burcs first make it. then make it great.↗

Calling it now: the trend of putting control flow in markdown for agents (skills, prompts, etc) is going to look *really* silly in a couple months↗

I reverse-engineered Instinct's memory. Here's exactly how it works Instinct has taken the world by storm over the last two weeks - it's one of the best imessage assistants I've used. as with every product, I decided to reverse-engineer Instinct's memory to find out exactly how…↗

what if copy/paste was smart? powered by @typesafeai jev it feels like every computer interaction will get rewritten↗

I spend ~2 hours a day programming, building side projects, tinkering obsessively, trying new repos.. I get basically a DM a day asking “aren’t you a VC, why are you doing this?” Unlike other eras, things are moving SO fast that if you don’t do this, I simply don’t understand h…↗

Powermove is out today. It's a video editor where the app itself is the thing you edit. The kernel is intentionally tiny. Timeline, effects, inspector, the UI, all of it lives in extensions on top. Ask the Powermove agent for a feature and it writes an extension, the same way we…↗

Introducing React Bits: Micro A brand new category for micro-interactions, launching with 30 free, customizable components. Smooth motion, subtle details, and playful interactions designed to make your UI feel alive. Live now. Try it out: reactbits.dev/c/micro↗

Made a skill for video demos /𝚟𝚒𝚍𝚎𝚘-𝚍𝚎𝚖𝚘 [𝚍𝚎𝚜𝚌𝚛𝚒𝚙𝚝𝚒𝚘𝚗] It records a video demo of your web app with zoom-ins and voiceover. You can keep asking for changes until you're happy with the video. github.com/nilbuild/video… Here's a one-shot video it generated �…↗

As part of improving everything, we've been rebuilding our 𝕏 Help Center from the ground up. Looking forward to this rolling out to all users in the coming weeks!↗

I just read what Zuck wrote about Muse connectors. A few things I think this means: 1. We’re witnessing the agentification of consumer apps. 2. Zuck believes Muse reaching 100M+ users feels entirely possible. 3. Whoever you connect to becomes your new landlord, so pick car…↗

today we announce something truly special introducing: Jesse v1 this model architecture is all new, from scratch, built and trained using public, popular datasets it consumes 0 tokens, and does not have weights it reasons, it believes, and it's very, very fast↗

I turned Jev into an image model…? Presenting Jevinci! github.com/achimala/jevin… The paintings are pure JS, no AI image-gen. Jev predicts every pixel's color in parallel and we paint them. The more confident Jev is in a prediction, the wider the brush. (sped up 4x)↗

Opening access for developers to build Muse connectors. You bring the API -- Muse brings the agent, the browser, and the context of what the person actually wants. People reach your service just by asking for it, and their agent takes it from there. New connectors are live today…↗

Looking for inspiration on what you are able to do with Jev (by @typefaceai) this weekend? Built a website called Jevable (jevable.com) which showcases all the fun demos on X - filterable by a few categories. Feel free to add your own project by using the + button!↗

Inspired by @typesafeai , here is a Jev-compatible public API to play with It runs a comparable open model (Qwen3.6-35B-A3B), and just uses SGLang radix cache to preserve the prefill reuse / really fast parallel systemone generation - 64 tasks in <1s. github.com/ekzhang/openje…↗

I've seen people describe Jev as an "AI if statement". But what if it actually WAS an if statement? Introducing Probably: a programming language powered by Jev: …bably-lang.southpolesteve.workers.dev Jev baked into the language. “feels” asks a question. “match” routes between d…↗

What is a decision model? Jev by @typesafeai answers yes/no and multiple-choice questions, with a confidence score. Much of software development are a sequence of decisions, and Jev is 10x cheaper and faster than an LLM. Let’s understand this through practical examples:↗

you can also use Jev to cut costs and token usage! make your agents more efficient by compacting shell and large file output before it reaches the LLM passing only necessary tokens to the model and carrying fewer tokens through the rest of the conversation↗

Jev is INSANE. 🤯 in 24.9 seconds it read 384 news from this morning and told 15 brands which stories to hop onto today, for $0.19. Claude Opus 5, running on the same feed at the same time, got through 4/384 and cost $0.77. per headline that is ~390x cheaper, and the answer co…↗

I’ve put a ton of tokens through Jev now, and...I have thoughts. 1. The big labs lost the script TypeSafe’s intro video says, “We’re building prod, not God” — and can I just say? Hell yeah. @typesafeai built something for engineers like me, so I can build products for people li…↗

jev class of models have no generative decoder loop, have bounded outputs, utilize parallel inference, & have extreme compression/efficiency incentives. this makes them perfect to run on device (this will happen soon). at that point you can put judgment into basically every exis…↗

We’re partnering with Accenture on independent evaluation of frontier AI—part of our recent commitment to embed evaluators at Anthropic. Both we and Accenture expect to invest at least $1 billion to build capacity in this area over the next five years. …↗
