Breaking: Browser Use + Jev = Ultrafast ⚡ Findings flights took 7s and cost only $0.0039 🤯 > new action space every step > DOM state space > small LLM fallback to type (this video is at 1x speed btw) Built a tiny open source browser agent. try it below ↓
Jev-cu
An experimental Codex skill and JavaScript runtime that has Jev pick macOS Accessibility elements and actions from text candidates, while local policy gates hold sensitive operations for human confirmation.

Highlights
- Jev chooses the element, action, completion state, and risk from interface text candidates; screenshots are never sent.
- Runs in dry-run by default, and delete, send, pay, authorize, upload, captcha, install, and system-settings actions stop at confirm.
- The app allowlist lives in scripts/policy.mjs, and adding an app requires editing it explicitly.
- Interface text is treated as data rather than instructions, and the skill does not bypass logins, paywalls, or captchas.
- Installs into ~/.codex/skills/jev-cu with npm run install-skill, and npm run p0 measures element-selection accuracy on recorded AX snapshots.
Quickstart
npm run install-skill
echo 'TYPESAFE_API_KEY=YOUR_API_KEY' > .env.local
npm testWatch out
MIT-licensed. Needs Codex desktop's cua_repl runtime and a TYPESAFE_API_KEY; it is experimental, its execution-policy limits require review, and the offline P0 evaluation still calls Jev.

A really smart switch statement
hype-free explanation of jev: jev does not replace gpt / claude jev is just a *really* smart switch statement like if 2016 ml classifiers got 2026 levels of intelligence it's a new* type of tool that will make a lot of workloads insanely fast, cheap, and accurate * = and by Show more
After co-inventing ChatGPT, I kept asking myself: why have superhuman chat models not led to AGI? I’ve spent the last 2 years in stealth building a new way to train models (RLCD), and a new type of frontier AI model that we are releasing today: Jev • 20-200x faster • 40-400x

The case against Jev-scored compaction
This is a terrible compaction strategy that fundamentally doesn't understand how compaction and context management work. Seems like a lot of people are confused so let's break this down. 1. Compaction isn't a filter The role of compaction is to clean up history to keep the Show more
found the perfect use case for @typesafeai Jev: instant compaction in 2026, why is compaction still a summarization prompt? Jev can make it instant by scoring every tool call and dropping what’s irrelevant
Classifying rows in DuckDB
I made a DuckDB extension where you can use @typesafeai 's Jev to do quick classification of rows in any csv/parquet file or duckdb table about 10sec for 1k rows ~ better than using an LLM, way more ergonomic than a classifier game-changing for data analysis!
