JevPilot — vijayprasath99
JevPilot is a real-time 2D autonomous highway runner and developer telemetry lab that steers a car with Jev or Clef System One decision models, charting latency, confidence, and steering choices in a live dashboard.

This is one of several Jev listings for the same project. The canonical entry is JevPilot — standardagents.
Highlights
- Runs a 60 FPS game loop that polls a System One endpoint for left, stay, or right steering decisions.
- Default polling interval is 500ms and is adjustable from 100ms to 1000ms.
- Telemetry dashboard charts latency with Chart.js and tracks SLA status such as STABLE 500ms.
- Supports Jev by TypeSafe AI plus Cloudflare Clef and Clef-flash through the /v1/systemone API.
- Zero-build architecture: native ES6 modules served by Express, Node.js 18 or higher, ISC license.
Questions about this entry
Short answers drawn from the linked project or page.
Any endpoint that exposes the System One API specification at /v1/systemone. The listed supported models are Jev by TypeSafe AI, Cloudflare Clef, and Cloudflare Clef-flash, with JEV_MODEL defaulting to clef-flash.
JevPilot is released under the ISC license, as shown by the license badge in the repository README.
The README describes single forward-pass decisions in tens to hundreds of milliseconds and carries a sub-100ms decisions SLA badge. The game polls the model on a tick interval that defaults to 500ms and can be tuned between 100ms and 1000ms.
Yes. JevPilot offers hybrid control that switches between autonomous autopilot and manual keyboard input at any millisecond with instant override. A developer sandbox and God Mode also let you toggle invulnerability shields and inspect decision payloads.
It is a 2D arcade game and telemetry sandbox for benchmarking decision models, not a production driving system. It ships no model itself, so you must supply a reachable System One endpoint and an API key, and it requires Node.js 18 or higher.
