we announced Jev 1.14 on 10.14 at 1:14pm PT 🔥
a new and improved model, along with experimental features for our dreamers:
• images
• a new box type
• longer context
surprise, Jev was already able to see you! 👁️
BUT our bar for production-grade intelligence is quite high, so builders beware, these are preview features.
enter the ~*~ danger zone ~*~ at your own risk. 🚨
where to use Jev? Jeverywhere!
(missed opportunity)
but seriously we've barely begun exploring the space of possible smart software and y'all are thinking small?
Having built many dozens of Jev-powered projects and demos over the past few months, I can say with confidence my #1 advice for how to use Jev is:
Just put Jev everywhere.
Every time I think of a new (not Jev specific) project, I think to myself "what could Jev do in this system to make it cooler/smarter/weirder/sillier/whateverer" and then I do it.
The objective is not to use it in places where it makes total sense. The objective is to continue to expand my mind to see Jev the way our long term vision has always been: as an enabler of a new kind of smart software. The more you train your brain to truly think of Jev as smart primitives that can slot in to code in anywhere a primitive could live, the more you find novel use-cases.
Don't stop building. Don't stop playing. Experiment forever and ever and have fun with it!
get those creative juices flowing

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! 🔗 ➡ 🧵
you too can learn to Jev the way @allietheicon Jevs!
new cookbooks hot & fresh every week.
One of my favorite Jev patterns is "line-by-line search", where you put an entire document in state, and ask a question for each line (or paragraph). This is super useful when you want to find the most relevant line for a query.
Use nouls when you expect one dominate answer, use scores when you want to highlight lines by overall relevance. The former is good for answering a specific question while the latter is good for finding all relevant passages.
today's is one of our old favorites

ever thought your agent was being a tool?
let Jev hand it the right tool for the job instead!
Introducing Jev Router for Agentic Tools ⚡
1. Connect your agent to 10,000+ tools and models in one MCP
2. @TypesafeAI’s Jev picks the best for your task
3. Result is 96% cheaper than Claude!
Try it with zero markup now > aimlapi.com/mcp
First 100 commenters will get a $10 promo code as early adopters!
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

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.
