Installation

Install the CLI

Pre-built and ready to use (Linux x86_64/aarch64 only today — other platforms fall through to cargo install below):

curl -LsSf https://paiml.com/apr/install.sh | sh

To read the script before it runs, download it with curl -LsSf https://paiml.com/apr/install.sh -o install.sh, review it, then run sh install.sh. The installer is POSIX sh and checks the downloaded release archive against its published .sha256 before installing.

Compile and build:

cargo install aprender

This installs the apr binary — a single command for inference, training, serving, model operations, and profiling.

apr --version
# apr 0.4.17
