Simulation environments with decision models

MuJoCo Franka arm stacking cubes: code proposes and simulates small moves, Jev picks moves, grasp, release and completion, vs Claude.

Deterministic 3D restaurant simulator that replays the same evening to compare rule-based, camera-assisted and Jev-planned waiters.

Simulated espresso bar where an XState machine defines what is possible and Jev chooses the barista's next event.

Chicago traffic simulator comparing fixed, adaptive and Jev-guided citywide signal policy on identical scenarios.

Toy archipelago air-traffic sim where each plane asks Jev every 1.6 s whether to divert, declare an emergency, give way or land.

Simulated Perseverance rover demo where Jev makes fast onboard hazard and science judgments, Claude plans, and code owns geometry.

Three.js drone simulator where Jev chooses each of nine candidate movements and estimates whether the route is blocked.

Simulation where Jev picks which of two conflicting signal phases gets green at a real Hong Kong junction from live open sensor data.

Experimental controller where Jev picks NES inputs for Super Mario Bros. from structured emulator RAM and telemetry, not screenshots.

Interactive Jev experiments, from a support-message decision lab to 3D self-driving demos with steer, speed and overtake decisions.

Fine-grained robot control on LIBERO tasks where Jev picks intent, motion family and input with local physics previews.

Experimental Minecraft bot where each TypeSafe decision picks one primitive action, which completed a 338-block flag build in recorded runs.

Browser MuJoCo Franka Panda workbench comparing Jev, Claude, OpenAI-compatible and local models on pick, stack and obstacle tasks.

Reinforcement-learning lab where cached Jev judgments act as reward signals for DQN agents on four classic control and grid games.

Multimodal robot decision SDK: camera images plus text go to Qwen3.5-9B with a corrective head that picks the next preset arm skill.

Harness where Jev plays the first StarCraft shareware mission from structured state, with recorded per-decision action probabilities.

Browser demo of village NPCs that make a typed Jev judgment each tick about what to do and how they feel.

Browser 1v1 shooter in the style of Krunker where Jev decides move, aim, aim-down-sights, fire and jump about nine times a second.

Simulated mouse colony whose behaviour is driven by Jev decisions on top of a deterministic engine.

X thread on a ViZDoom agent using two Jev decision channels: navigation at 5 Hz and combat at 12 Hz.
