Game & Simulation

3D chess game where Jev plays one or both sides, with several difficulty levels.

Unity Behavior action node that gets finite-outcome Jev decisions through an authenticated Node gateway with revision checks.

Six recorded chess experiments with Jev via OpenRouter, candidly showing that unaided Jev still blunders pieces.

Fully local grid tactics game where the open NanoJev model picks each move, attack, heal or dash from real candidate actions.

Factorio agent on FLE where Jev picks goals, next actions and stuck detection while code owns rules and actuation.

Craftax survival agent where Jev picks one Choice per step from code-listed actions, with optional LLM goals, plus ablations.

Snake research environment where game rules stay in code and Jev picks the movement direction from structured state each tick.

StarCraft II research repo where Jev Choices pick macro actions and unit micromanagement, optionally constrained by a larger model's plan.

Tetris where each reachable placement is an English sentence that Jev ranks, with controls showing a regex baseline does better.

Evaluates Jev as a fixed policy in Gymnasium and Atari games, picking a legal action each step via one Choice question.

Mineflayer Minecraft bot where code lists feasible actions and Jev picks one in about 0.2 s; 15 of 40 runs reached the Nether.

Traffic signal controller where Jev picks each intersection's next phase from a SUMO snapshot, with local fallbacks.

Embodied Minecraft agent where a typed decision plane (Jev or Liquid d1) picks grounded transitions and a kernel owns verification.

Model Kombat: a 12,000-neuron fly connectome fights Jev in mk.js, with Jev picking one of seven moves about five times a second.

Pandu: tiny local policy networks (2.9K-5K parameters) with calibrated uncertainty that fall back to a teacher when unsure.

Chinese Slay the Spire 2 agent research: code handles rules, cheap Jev makes most choices, a stronger model takes key moments.

Tic-tac-toe teaching project comparing Jev Choice, Score and Noul designs across three levels of state detail.

Audience simulator where 10,000 computed personas read your post or listing and Jev decides who sees it and how each reacts.

Pokémon Red on PyBoy where code owns route and arithmetic, Jev picks only at branches, and battle faint predictions are Brier-scored.

Local Snake battle where four NanoJev AI snakes pick moves from a candidate distribution while you play the fifth.

Pygame chess where python-chess owns the rules and Jev picks one labelled legal move per turn, with Human or Jev on either side.
