Jev plays Factorio
A Python experiment that lets TypeSafe's Jev play Factorio from screenshots alone: each tick the vision model looks at the screen, decides, and presses keys or moves the mouse, aiming to craft 10 automation science packs from a fresh freeplay game.

Highlights
- Jev is a vision model behind the Typesafe SDK here, playing from screenshots alone with no game-state access.
- Current goal: from a fresh freeplay game, craft 10 automation science packs (red science).
- The author's one-run video title says Jev reached 10 red science for $0.11.
- Requirements: Windows, Factorio 2.0, a 1920x1080 windowed client, Python 3.12, uv, ffmpeg and a Typesafe API key.
- Each run writes decisions.jsonl, screenshots, state.json and a recording into a runs/ folder.
Quickstart
bash
uv sync
cp .env.example .env
uv run python -m jev_factorio.loop --policy play --goal red_science --seconds 1800Watch out
README reviewed 2026-10-17; the $0.11 figure comes from the author's linked video title, not a benchmark, the project is Windows-only due to Win32 input handling, and no license is listed in the repository metadata.

An experiment that gets TypeSafe's Jev to play Factorio. Jev is used as a vision model: each tick it looks at the screen, decides, and presses keys or moves the mouse, with no direct access to game state.
From a fresh freeplay game, craft 10 automation science packs, the red science goal, per the README. A linked video shows Jev reaching that goal in one run for $0.11, according to the video title.
Jev is a vision model behind the Typesafe SDK in this setup. The README says it plays from screenshots alone, deciding each tick and acting through keyboard and mouse input.
Windows, because input and window handling use the Win32 API; Factorio 2.0 with Space Age, windowed at 1920x1080 at the top-left; Python 3.12 and uv; ffmpeg on the PATH; and a Typesafe API key.
After uv sync and adding your key to .env, start a new freeplay game and run uv run python -m jev_factorio.loop --policy play --goal red_science --seconds 1800. The loop pauses when Factorio loses focus, and End stops it.
A folder per run inside runs/ with every decision in decisions.jsonl, the screenshots, the game state in state.json and a recording, per the README.
