Build From Source

vex builds as a local CLI binary, but it does not bundle a model runtime. Before you start, make sure you have:

  • Git and a stable Rust toolchain on your PATH
  • permission to clone into a writable directory and create .vex/ files plus AGENTS.md inside it
  • a reachable model endpoint

Use a local server on http://127.0.0.1:8080/v1 when you want the fastest same-machine setup. Local and private-network endpoints can stay on plain HTTP and do not need VEX_MODEL_TOKEN. Use a remote public endpoint only when it is exposed over https://; those endpoints require VEX_MODEL_TOKEN. For alternative endpoint wiring through api_client.base_url, see Configuration.
