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,
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

Jev brings reliable intelligent judgment to @UiPath workflows, about an order of magnitude cheaper and faster LLM-as-a-judge-no-more
Meet the @typesafeai connector in UiPath Integration Service. 🔗 Bring Jev models into your workflows to make fast, confident decisions at lower cost & latency: uipath.com/blog/product-a…
let's be real, cookie banners were a terrible idea what should get automated away next?
We put Jev inside the Lightpanda binary and built judge() on top of it. @typesafeai No more sending a whole page to an LLM just to find out it's a cookie banner. > Blocked pages, CAPTCHAs, cookie walls, logins, paywalls, error pages, empty searches and pages still loading can
the creativity and productivity coming out of @coderabbitai 's Jev hackathon was nuts. lots of great tidbits in their video!
Congrats to TypesafeAI on the Series A! At the first ever Jevathon, we watched developers build some seriously impressive apps on their new System One model. Can't wait to see what's next!
@postimortem our swag moves in mysterious ways
can we offer you a TypeGlizzy in these trying times?
hmm maybe a benchmark is okay if it makes you hungry
Is this a hot dog? find out what your favorite LLMs said over at hotdogbench.com
who benchmarks the benchmarkers? a good eval is: - ephemeral. it snapshots a moment in time and capabilities. - grounded. it directly measures performance on tasks and data you care about. - specific. it operates on the desired results and not some proxy of them. take notes!
Typesafe's CEO @CompleteSkeptic does not trust public benchmarks. Neither do I, Diogo. So @p0 and I wrote a blog evaluating 8 decision models on real company training datasets we have personally audited and iterated on. For what it's worth though, Jev is still on top 👑
pouring one out for everybody who thought einstein was running their agent and came back to mr bean
(cmd-) f the world indexing got you down? can't find your keys? f that. no really, f that Jev's got your back (demo replay for those who missed JevDay!)
our CEO @CompleteSkeptic tells the tale of Dr. Einstein and Mr. Bean > if AI responds like Einstein 95% of the time and Mr. Bean 5% of the time, how are you going to automate anything with it? @mattturck talks us through a wild first month of Jev
Crazy launch! Copycats! Massive round! On the one-month anniversary of the launch of Jev, we unpack it all with @CompleteSkeptic, CEO of @typesafeai: what Jev is, how it fixes what's broken in AI, and why the fast-followers are missing the hard part. 00:00 “95% Einstein, 5% Mr.
not a second stopped in bat country
Jev can cross America navigating by street signs alone Here's it completing the Cannonball Run from NYC to LA, picking a direction at every turn, given just a destination address and the name of the street it's on
Jev 1.14 is now on OpenRouter. Per @typesafeai this release is "beautifully boring": • Everything: a tiny bit better • Multilingual: the biggest upgrade • Multimodal: it can see now (experimental) • Price: unchanged ($0.042/M input, output free) • Drama: none openrouter.ai/typesafe/jev-1…
Filtering is the expensive half of a news digest. Every article needs a judgment call, and a judgment call has always meant an LLM call. Not anymore. $0.00004 per article. We teamed up with @n8n_io and built a weekday AI brief using @typesafeai's Jev. Now live on n8n blog as part of their Verified Node Spotlight. 🧵
funny, suddenly all of these dynamic designs, structured workflows, and knowledge task solutions are appearing faster and faster, as though it were dramatically easier to automate them. wonder what happened 🤔 great work @Lovable
If your app doesn’t have AI features you’re ngmi We made them simple to build: just ask Lovable. Now powered by even more models from @claudeai, @firecrawl, @GeminiApp, @OpenAI, @perplexity_ai, @p0, and @typesafeai.
