Jev Browser

A browser WebGPU export of Julia 1: the same 551 MB decision checkpoint, a Rust WASM tokenizer, and a JavaScript API that answers typed questions client-side with no server or key.

A 400M-parameter Jev-compatible decision model with a browser build: 0.796 on typed decisions against Laya's 0.766, 17 ms per question on an L40S, and an ONNX file that runs in a tab.

Apache-2.0 decision models for browser agents: a Qwen3.5-35B-A3B fine-tune that answers jev-ultrafast's per-step operation and target-element Choice questions in one forward pass behind a Jev-compatible /v1/systemone API. Includes training code, a serving stack and a 125-task real-website evaluation.

A Playwright-based CodexQA skill where Jev chooses indexed controls on a page-built index while the browser executes the action.

A CLI browser automation tool with optional Jev semantic mode: Surf observes, Jev selects the next action, Surf validates and acts, Jev checks the goal.

A Next.js input box that morphs into the right UI as you type, using Jev to answer 14 intent questions in one call while deterministic code computes the values.

A skeptical computer-use test of Jev with a public test repository, from Builder.io's Steve.

Ground Truth, a browser extension that shows the political framing, article type, topic, and loaded language of the news article you are reading.

Browser Use's ultrafast agent: Jev picks an operation and an element from an indexed action space in one request, and a small LLM writes text only when the action is TYPE_TEXT.

Chrome and Firefox extension that reads a YouTube video's caption track and asks Jev for a sponsor probability per 30-second segment, painting the seek bar before the intro ends. It reports catching 77% of SponsorBlock's sponsor seconds across 23 videos at $0.0008 per video.

Unofficial Chrome Manifest V3 port of browser-use/jev-ultrafast: Jev picks the operation and DOM element in one request, a small text model writes typed values, and the run happens in your own tab with your logins. Ships a 17-task headless-Chromium suite.

WXT Chrome and Firefox extension that has Jev classify nonessential page elements through TypeSafe or Vercel AI Gateway, then stores reusable local hiding rules by page template. Paid analysis is manual by default, with an optional on-visit mode.

Local Instagram, TikTok, and LinkedIn research app where Jev makes confidence-gated typed choices over the platform and next socai operation, while deterministic Node code validates each decision and the socai CLI performs read-only browser capture.

A Manifest V3 Chrome extension that finds ad-shaped DOM elements and asks Jev, one noul question per candidate, whether each is a paid advertisement; hits above the threshold are removed.

A Codex skill (with a plugin option) that hands clicks, toggles, navigation, and scrolling to Jev over accessibility text while Codex types, interprets visuals, and verifies the outcome.

Unofficial browser automation where the calling LLM states the outcome and Jev decides each element, action, and value from a Playwright page snapshot. Ships as a library, CLI, and MCP server.

A TypeScript browser agent for ego lite that turns one natural-language goal into CLICK, TYPE_TEXT, or SELECT on a numbered element table, with Jev choosing the operation and target in one request.

Two WebAssembly builds of the Chocolate Doom 3.1.1 engine play the same Freedoom map from the same initial state, with a Jev Choice decision picking each tactical macro and a local controller turning it into inputs.

A browser tool that checks whether a cited paper supports the sentence citing it: code matches references and verifies quotes, Claude proposes an evidence passage, and Jev scores supports, contradicts, or says nothing.

A tldraw canvas controlled by voice and a webcam-tracked fingertip: every partial transcript triggers one Jev request through OpenRouter's Decisions API that decides the action, shape, colour, and place.

An original Civilization II browser harness for Jev: named Choice vectors cover empire policy, cities, research, diplomacy, units, exploration, and warfare, with live decision probabilities in a Roman-themed spectator display.

A reproducible harness that scores Jev Ultrafast research-browser runs over 11 baseline cases plus human and quant stress suites with CoS-locked QC grades, regenerating the field note and trace notebooks offline.

A Chrome extension and small web app that skips YouTube sponsor reads: Jev names transcript lines or answers yes/no about what it heard, and code owns every timestamp that gets cut.

WXT Chrome extension that grades readable page sections with Jev through Vercel AI Gateway, giving each section ten rubric scores and each page an inspectable A-E grade.

A Chrome side panel that turns the current page's WebMCP tool schemas into typed Jev questions, predicting the tool call, its arguments, confidence, and latency as you type.

An open-source browser agent extension for Chrome and Edge that browses, fills forms, clicks, and collects data, letting any extension-capable browser act as an AI browser with your own LLM key.

A local browser agent that reads social media by driving your signed-in Chrome across Xiaohongshu, TikTok/Douyin, Instagram, and LinkedIn; a companion Jev Social demo lets Jev choose bounded socai CLI operations and produce a source-linked report.

A Chrome and Firefox extension that scores a draft X post with Jev before posting: virality, clarity, ragebait, insult level, regret risk, and typo detection, plus a Send it / Sleep on it verdict.

Delegated browser execution for parent agents: Jev picks one bounded typed action from the current page snapshot, agent-browser performs it, and ambiguous or stuck flows escalate back to the parent.

A browser-use agent where Jev picks one action per step from a page's interactive elements. Runs as an MCP server, CLI, or library and returns a step trace, screenshot, and console errors.

Control a headed Chromium window by voice: one Jev request per partial transcript decides intent, target, and completeness in roughly 300 ms, while code applies thresholds and builds the action.

Kyle Jeong's demo of browser use with Jev and Stagehand: the accessibility tree is the state, actions are the questions, and one remote-browser task cost $0.001 at near-instant speed.

dax previews how fast browser use can be with Jev as the decision layer and OpenCode's browser-use CLI, quote-posting a demo video of the loop in action.

Browser Use's Ultrafast agent puts Jev in charge of picking each browser action from a dynamic DOM action space. The author reports a flight search in 7 seconds for about $0.0039.

The WebMCP benchmark author reports that Jev paired with the small Mercury 2.5 model solved 100% of tasks at roughly 112x lower model cost than GPT-6 Astra with computer use.
