jev will make agents 10x faster and cheaper, here's how:
1/ model routing: pick the right model for each task, without training a custom router

2/ computer use: faster, cheaper and more reliable for action-heavy tasks
https://x.com/gregpr07/status/2100411066966749359
3/ auto review: ask jev whether an action is safe, instead of using a slow and expensive LLM

4/ less obvious: subagent orchestration
long-running agents (cursor projects, grokbot, energy) parallelize work with subagents.
but every user message, email, or subagent reply can wake the expensive orchestrator.
example: it costs $1 to wake up gpt 6 astra w 100k input tokens
jev can decide what each event needs:
- route directly to a subagent
- queue for later
- wake the orchestrator
Jev is HERE and this is the CLEAREST explanation of what it is and what NEW businesses it unlocks.
(and at the end I'll tell you how to get Jev even if you're on the waitlist)
WHAT IT IS
You know how you open your inbox and have to decide what's junk, what needs a reply, and what can wait? Jev does that part. It looks at each thing and says "this is junk, I'm 94% sure."
It doesn't write anything back to you. It just sorts.
1,700 emails for 18 cents, instantly.
That sounds kinda trivial but the important part
WHAT IT UNLOCKS
My explanation of Jev sounds small until you realize HOW MANY jobs are exactly this. Someone reading a stack of applications. Someone deciding which support ticket goes to which team. Someone looking at inbound and deciding who's worth calling back.
A few ideas on what it unlocks:
1/ Instant quotes that are actually instant. Every quote form on the internet says "we'll email you by end of day." Build the version that answers in under a second, for roofers, movers, insurance, legal intake.
2/ Lead scoring as a product. Every agency and service business has a contact form full of junk. Score every submission and send the real ones straight to the owner's phone.
3/ Support triage for companies with no support team. The ticket gets classified and routed before anyone opens it.
4/ Clipping tools. Pass in a transcript, get the best moments scored in three seconds. Every clipping product just got a cheaper engine.
5/ Application piles. Grants, permits, insurance claims, job apps, loan docs. Someone reads that stack one item at a time today.
6/ Marketplace matching. Someone types what they need and gets matched to the right local business instantly instead of waiting for callbacks.
7/ Browser agents that actually move FAST. That makes bulk browser work practical: pulling quotes from five carriers, filing the same form for 200 clients, checking supplier inventory in real time etc.
TLDR; find an expensive queue and put Jev at the front of it.
HOW TO GET IT
I didn't realize you can skip the waitlist because Jev is live on the Vercel AI Gateway right now, so you can start calling it today. In this episode, we share how.
Episode now live on @startupideaspod (thanks to @ryanvogel for coming on and spilling the sauce today)

Jev is a big deal because this is a whole new way to do AI
Really cool
Happy Jev day.
