Jev in the wild: seven community builds

Jev builders have been busy. Browser agents, branching Mario worlds, a driving simulator, a canvas you control by talking and pointing. Here are seven builds worth looking at.

Browser Use’s Jev Ultrafast picks an operation and a page element together. A separate model writes text when needed. Its published flight-search demo took seven-point-one seconds, after the first page observation. One task, not a universal benchmark.

Mario Never Dies forks a checkpoint into four virtual machines after a death. Each tries a different recovery, then hands control back to Jev. A surviving branch becomes the ongoing run.

Standard Agents’ Pokémon Red experiment reached the Hall of Fame on September twenty-third. Jev played, while Opus five monitored logs and rebuilt the harness along the way. The combination matters.

JevPilot lets Jev choose steering and speed from candidate paths. Local code handles geometry, collision checks, and braking. You can inspect the choices while the simulated car moves.

Jev Canvas combines speech and a pointing finger. Say where a shape should go; Jev chooses the action, target, and place. Speech recognition and hand tracking supply the inputs.

Fast Jev Compaction scores which tool calls and results to keep, truncate, or drop. Fully retained material stays verbatim. Useful idea, but deciding what to discard can still lose something important.

LangChain shows Jev choosing models and checking risky tool calls before execution. These are building blocks for an agent harness, with probabilities available for inspection.

The common thread is specific choices inside working software. Jev returns typed decisions and probabilities. The app still owns the actions, the checks, and what happens when a decision is wrong.
