An AI lab building intelligence beyond chat.

We have seen such an immense swell of demand that we have to temporarily pause signups for Jev. We need to ensure quality of service for our existing signups, which will continue to function. We are working diligently to ensure open access to Jev for everyone as soon as we can. Thank you.

We couldn't do what we do @typesafeai without our partners at @modal 🙏 thanks Modal team!

SO MUCH THIS I believe that one of jev's greatest benefits to automation will come from resurrecting architecture best practices: state management, encapsulation, abstraction !!!! and combining them with ML's best practices: measure/evaluate, use calibration/uncertainty (adding screenshot b/c I don't know how to quote 2 posts 🤦)

remember this old post of mine? Tried it with Jev---it seems to have a grasp of the globe on par with some of the best models a year ago due to the architecture & low cost, it was also feasible to extract a labeled map of continents and countries. lots of interesting details
new post. there's a lot in it. i suggest you check it out

You've never routed like this before. @OpenRouter is bringing Jev to all of your LLM calls, so your agentic workflows never have to waste a token again. As always, faster, cheaper, more intelligent. Go build the future.
Introducing typesafe/jev-router: a cache-aware model router powered by Jev and @typesafeai The Jev Router picks the best model and reasoning effort for each request, balancing quality, speed, and cost. Here's how it works 👇🏻

DSPy methodology 🤝 System One Program, don't prompt!
DSPy 3.4.0 was just released! This release includes native support for Jev and System one models inside of DSPy! Use it with compatible signatures. This release also includes a brand new optimizer, ReAnchor, specifically for calibrating outputs with confidence.

Jev generally out-performed frontier LLMs at a fraction of the price: Repeat-question matching: 70% → 97% Expense categorization: 50% → 86% (vs human reviewers) Escalation: same catches, fewer false alarms

Speed was measured while shadowing live production traffic: up to 4× faster. Offline tests: 2 to 3×.

Some great use cases they measured: • Matching repeat analytics questions to approved answers • Picking 1 of 36 metrics • Blocking PII requests • Deciding when a support chat needs a human • Tagging tickets across a 3-level taxonomy • Sorting expenses into about 55 categories Every one is a pick from a known set.

Jev is having a moment. Every platform rushed to host it the same way: another model endpoint in the catalog, and good luck wiring it into your agent loop yourself. We took a different route at DigitalOcean. In addition to Jev being available in our Inference engine, Jev is also available inside Action Gateway as a first-class classifier tool, right next to browser automation, and 16,000+ other tools behind one governed MCP endpoint. That distinction sounds small. It isn't. Treat Jev as a model and your agent's LLM has to know about a second inference provider, manage another API key, and hand-roll the request plumbing. Treat it as a tool and any harness you already run (Codex, Claude Code, LangGraph) just discovers it and calls it, same as any other tool in the belt. Ask typed questions: a yes/no, a choice from your own list, a score on your own scale. Get back decisions with calibrated probabilities, schema conformance guaranteed. Answers land as data your code uses directly, so agents route, filter, and escalate without parsing prose. The gateway part matters too. Jev calls ride the same governance as everything else: scoped permissions, credentials that never enter the model context, low-confidence answers flagged for a human, every decision in the audit trail. We ran a Codex agent through it this week. One YAML, one prompt, and it turned a day of X noise into a shortlist worth reading, with the uncertainty left visible. If you want raw inference, Jev is on Serverless Inference too, at $42 per billion input tokens with output free. But agents shouldn't have to treat a classifier like a chatbot. Models reason. Jev decides. Ship both. On the same platform.

On Sept 30 we’re working with @supabase to put on HYPERSHIP DAY on Product Hunt. If you think you can build and ship fast, and you haven’t launched recently, submit your launch by midnight Sept 30. We’ll be providing some cool prizes including Jev credits and swag! And if you’re not launching: Mark your calendars to try new products, make feature requests, and watch the products evolve over the course of the day. 🔥🔥
Sep 30 is **HYPERSHIP** day on Product Hunt. If you think you can build and ship fast, and you haven't launched recently, submit your launch by midnight Sep 30. Be prepared to build and ship multiple features in real-time. Appropriately, given the speed theme, we’ve partnered with @typesafeai, makers of Jev, a frontier model at real-time speed, and @supabase, the backend platform you know and love! Prizes will include Jev and Supabase credits, swag boxes, and secret prizes we’ll announce later. And if you're not launching: Mark your calendars to try new products, make feature requests, and watch the products evolve over the course of the day. This is the day where we redefine what shipping velocity means.

Relevance is great, but relevance to what? Jev gives you search intelligence that no canned SEO can 🪱 its way into.
I built JevSearch, search the web & validate your results with Jev. Give a query and selection criteria, use @browserbase search to get the t25 results, then Jev scores and returns the t5 results. Jev often chooses urls outside of the initial top 5 as more relevant.
