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 > First 100 commenters will get a $10 promo code as early adopters!

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

the people want swag. we hear you. so naturally: free ice cream instead. @Judgmentlabs is celebrating with free ice cream and we'll be serving scoops of Jev-Jam! 235 Pine St, San Francisco Tuesday, Oct. 27, 11 a.m-1:15 p.m

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.

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 for agents. Millions of users and developers already use Composio as the runtime for their agents - giving agents tools, auth, and sandboxed execution. Now with our agent firewall every action an agent takes is evaluated using Jev and custom SLMs tuned by Composio based on real-world usage data. The firewall strengthens that existing boundary in both directions, checking the actions agents take and the information coming back to them through Composio. The advantage of the runtime boundary is that Composio Firewall verifies that the agent respects user intent and the boundaries set by the developer and user. Additionally, this provides the safety layer required to protect the user against malicious prompt injection as well as other attacks. Composio Firewall is live now for all Composio developers.

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 all return an HTTP 200 > judge() asks a set of predefined questions and tells you if the page has real content, and what kind: article, listing, product or docs > One call, ~0.2s In the video: > 30 sites, ~14s total > Lightpanda backs off when rate-limited, accepts cookie walls, and keeps or skips each page

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!

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 👑
