What if we could manipulate UI at the speed of thought? Built this voice coffee ordering system with @typesafeai Jev. The drink and any updates show up while I’m still mid-sentence, ~200 ms from word to screen. Feels pretty magical!

Can't stop thinking how much stuff Jev is doing to save AI engineers asses from stupid systems design patterns while the rest of the domain keeps pushing tool calling loops everywhere
oh so everybody vibecoding their own app is easy now? just a slop cannon away from everything you want in life? prove it! hypership your dreams into reality today
Hypership is BACK for our 13th birthday!! Celebrate with us by requesting features and reporting bugs on the launches featured on today's leaderboard. To those who ship, you have a chance to win credits from @typesafeai and @supabase! Makers, how fast can you get features to prod?

what did they mean by this
Straight to onsite. I have to know.
build it fast. build the right thing. HYPERSHIP on @ProductHunt, this friday.
Two days to get yourself onto the HYPERSHIP board. @supabase and @typesafeai are both back with credits, and the day runs on you launching, taking the requests that land and shipping them before midnight.

One thing that can be tricky to figure out is how to use Jev's primitives to handle more than one intent in a single user query. My favorite way to approach this is what I call the "shopping cart" pattern: recursively pick the next thing until Jev says we're done. I've personally used this to make a coffee ordering bot for our company Slack (using @DoorDash's CLI!), as well as a fast multi-intent handler for my smart home system. Give it a shot!

Why Jev epitomizes what a great brand is today “Everyone wants to clone Jev. No one wants to get up on stage, wear a fucking pink fur coat and talk about the Jevolution in an unhinged way. That is what brand is to me. That guy is playing the game on a whole different level. Companies today have to think about that.” @bernhardsson Love to hear your thoughts @CompleteSkeptic @sonyatweetybird @davegerhardt

can you smell that? it's thousands of developers pushing to prod on a friday like god intended, thanks to @ProductHunt we'll be seeing you november 6
HYPERSHIP day returns Nov 6, with @typesafeai and @supabase putting more credits on the line! Submit your launch, and build and ship features in real-time as the requests land to earn extra points. Last time around, over 8,000 points were awarded 👀

In a Discord town hall a few weeks back, I talked about Intelliprompter: my first-ever AI-integrated personal project. I had shelved it due to LLM costs, but revived it the day I first learned about Jev. We now have a Cookbook up on our docs showing how to make your own! 🔗 ➡ 🧵

for years, better tech has meant more bloat, slower and less responsive websites and apps, confusing and confused interfaces weird how AI has continued that trend. real weird. not anymore.
Things are getting serious @typesafeai Jev now handles logins in Lightpanda's agent. It picks the username field, password field and submit button from the page. > Jev: 0.53s, 2 calls > Claude Haiku 5.5 with browser tools: 7.83s, 8 tool calls

check out what workday's been doing with Jev! link below
bespoke agents, with bespoke knowledge bases, bespoke instructions, bespoke tool-sets, and of course, bespoke routing with Jev make your goon your very own!
It has been interesting to see all the applications of @typesafeai's Jev at @sanity_io. Like our new internal agent harness which allows anyone in the company to quickly spin up a bespoke agent. Jev is used for the router and has worked pretty well so far! We (@rostimelk, @even, and I) wrote up an in-depth post about how it's built so you can do it too.

for trust issues, sometimes you need therapy but your agents need a reliable code firewall, powered by Jev
Agents have a trust problem. Today’s models can do most work. What they need is the right boundaries. In traditional software, those were set at build time. With agents, they have to be set and enforced at runtime. Today we’re introducing Composio Firewall, the runtime boundary for agents. Millions of users and developers already use Composio as the runtime for their agents - giving agents tools, auth, and sandboxed execution. Now with our agent firewall every action an agent takes is evaluated using Jev and custom SLMs tuned by Composio based on real-world usage data. The firewall strengthens that existing boundary in both directions, checking the actions agents take and the information coming back to them through Composio. The advantage of the runtime boundary is that Composio Firewall verifies that the agent respects user intent and the boundaries set by the developer and user. Additionally, this provides the safety layer required to protect the user against malicious prompt injection as well as other attacks. Composio Firewall is live now for all Composio developers.
