Linux on ARM (arm64): use openjevx-linux-arm64.tar instead.

Windows: download openjevx-windows-amd64.zip and openjevx-model-0.5.2.tar.gz, unpack both into the same folder (tar -xzf openjevx-model-0.5.2.tar.gz) and run openjevx.exe.

OPENJEVX_PASSWORD=<12+ characters> OPENJEVX_API_KEY=<16+ characters> docker compose up -d --build

Talk to it from jevx

shell

jevx profile add openjevx http://127.0.0.1:21160/v1/systemone --model openjevx
jevx profile use openjevx
jevx is "Is this urgent?" < email.txt

What it is

Default port 21160, endpoint /v1/systemone. device is auto, cpu, or gpu in openjevx.json.

Dashboard

Open http://127.0.0.1:21160/ while it runs: request counts, latency p50/p95/p99, errors, recent requests. No default password: set "password", or read the one the server generates into openjevx.password.
