Jev is HERE. How to use it

Greg Isenberg28m 25s

Jev is a new AI classifier model created by Dooo Almeida that makes fast, low-cost decisions on structured inputs rather than generating text like traditional LLMs. It processes information through a defined schema to return probability-based classifications across multiple categories, enabling applications from email triage to content clipping to flight booking automation.

Summary

The podcast features Ryan Vogle from the founding team of Open Code explaining Jev, a fundamentally different type of AI that functions as a decision-making classifier rather than a conversational language model. Unlike LLMs that predict the next token and stream responses, Jev takes a defined input, evaluates it against a schema of possible outputs, and returns probability scores for each option—for example, categorizing an email as 80% spam, 10% marketing, 10% finance.

Ryan demonstrates Jev's capabilities through a practical email classification example where 1,700 emails were categorized across four dimensions (category, priority, spam score, and reply percentage) for just 18 cents. This illustrates Jev's key advantages: exceptional speed (approximately 200 milliseconds per query regardless of complexity), extremely low cost (demonstrated with a $5 credit sustaining heavy usage for 2 days), and type-safe structured outputs that integrate directly into code.

The conversation explores multiple business applications: email lead filtering for a graphic design agency, support ticket triage and routing, form-based instant quoting for service businesses, YouTube video clip extraction by identifying interesting moments in transcripts, and browser automation for travel booking. Ryan emphasizes that any workflow involving human decision-making on incoming data could benefit from Jev's instant classification.

Ryan acknowledges limitations, noting that Jev performed poorly on Bitcoin trading signals compared to GPT-4o, suggesting it excels at routing and classification decisions rather than complex reasoning tasks. He characterizes Jev as a decision model specifically, not a general-purpose reasoning system, and demonstrates creative applications like using letter-by-letter classification to generate text, though noting this isn't Jev's primary strength.

The episode concludes with access information: Jev is available through the Vercel gateway for immediate testing, and users are encouraged to identify workflows in their own businesses that could benefit from fast, cheap classification automation.

About this episode

In this episode, I talk with Ryan Vogel about Jev, a new type of AI built for classification. Ryan shows how Jev takes an input plus an output schema and returns a probability for each choice in about 200 milliseconds. He demos Jev sorting 1,700 emails for 18 cents total, then covers lead scoring, support routing, video clipping, and browser control. I push him on the startup angle: find a business with an expensive queue of incoming information and put Jev at the front of it. You leave with a clear mental model, real use cases, and a simple way to try it today.

Numbered Section Summaries 1. What Jev Actually Is Ryan explains Jev as a classifier. You define an input and an output schema, and Jev returns a probability for each option, for example 80% orange, 10% red, and 10% blue for the color of an iPhone. 2. The 18-Cent Email Demo Ryan runs Jev on 1,700 of his own emails and scores each one for category, priority, spam score, and reply likelihood. The run uses 4.2 million input tokens and 500,000 output tokens and costs 18 cents total. 3. A Decision Model, Distinct From a Chat Model Jev returns only structured output, meaning the numbers and categories from your schema, with zero visible reasoning. Developers can drop that type-safe output straight into code. Ryan also tests Jev as a letter-by-letter text generator to show how a decision model differs from a chat model. 4. Cheap Enough to Experiment A $5 intro credit lasts Ryan's team two days of heavy use, and he estimates $10 could last about three months. His girlfriend's graphic design agency uses Jev to score contact-form leads on a scale from 0 to 1, so high-value leads get a fast reply. 5. The AI Traffic Cop I frame Jev as a traffic cop: information comes in, and Jev decides what it is, how important it is, and what happens next. A high-confidence lead goes to a human, a lower score goes to automation or an LLM, and the lowest scores get ignored. Ryan adds support routing, where 200-millisecond answers replace slow streaming responses. 6. Put Jev at the Front of the Queue I ask how to find a business with an expensive queue of incoming information and put Jev at the front of it. Ryan describes a local services platform that matches a request like "I need my driveway power washed" to the best nearby business and turns "instant quote" forms into truly instant quotes. 7. Where Jev Struggles Ryan's Bitcoin test, which asks Jev to buy, hold, or sell every minute, performs poorly. OpenAI's latest frontier model does a little better because it cross-references news. Ryan's advice: use Jev for routing-style decisions and keep it away from your portfolio. 8. Clips, Browser Control, and Getting Started Ryan's video clipper scores 17 moments in about three seconds, and he builds it in about 10 minutes. A Browser Use demo shows Jev picking a flight from Zurich to London in 7.1 seconds. To start, use the Vercel Gateway and ask your AI agent which of your daily workflows could use a decision maker like Jev.

Key Insights

  • Jev processes 1,700 emails with complete categorization across multiple dimensions for 18 cents, with 4.2 million input tokens and 500,000 output tokens, demonstrating the dramatic cost advantage over traditional LLM-based solutions
  • Jev returns probability distributions rather than binary decisions—for example, 80% orange with 10% red and 10% blue—allowing for confidence-weighted classifications that reflect uncertainty rather than false certainty
  • All Jev queries complete in approximately 200 milliseconds regardless of input/output complexity, compared to traditional AI that can take 30 seconds and requires streaming listeners, enabling real-time decision routing in applications
  • Jev doesn't generate text or perform internal reasoning—it only returns structured data matching the defined schema, which distinguishes it from LLMs but also limits its application to decisions that don't require complex explanation or reasoning
  • A browser automation agent using Jev selected a flight from Zurich to London in 7.1 seconds, compared to minutes for other browser-use AI agents, demonstrating speed advantages in sequential decision-making tasks
