Brev

Brev

NVIDIA Brev provides on-demand GPU instances across multiple cloud providers. Instances come pre-loaded with NVIDIA drivers, CUDA, Docker, and NVIDIA Container Toolkit.

Brev is instance-based (not job-based). You create an instance, run commands on it via brev exec, and delete it when done. The TAO SDK's BrevHandler wraps this into the standard job interface.

Preflight

This skill needs the brev CLI and an active login. Check before proceeding:

# 1. brev CLI installed
command -v brev >/dev/null 2>&1 || {
  echo "MISSING: brev CLI not installed. Install:"
  echo "  https://docs.nvidia.com/brev/"
  exit 1
}

# 2. brev command reference available.
brev --help >/dev/null || {
  echo "MISSING: brev CLI help unavailable; verify the brev installation."
  exit 1
}

# 3. brev login active — always token-login first when running headless.
#    Plain `brev ls` will hit an interactive auth prompt (read: EOF on stdin)
#    even when BREV_API_TOKEN is set, so refresh the session up front.
if [ -n "$BREV_API_TOKEN" ]; then
  brev login --token "$BREV_API_TOKEN" >/dev/null 2>&1 || {
    echo "MISSING: brev token login failed. Verify BREV_API_TOKEN."
    exit 1
  }
fi
# Retry once after a forced re-login: cached creds occasionally desync and the
# first `brev ls` returns auth EOF until the session is rebuilt.
brev ls >/dev/null 2>&1 || {
  [ -n "$BREV_API_TOKEN" ] && brev login --token "$BREV_API_TOKEN" >/dev/null 2>&1
  brev ls >/dev/null 2>&1 || {
    echo "MISSING: not logged in to brev. Run:"
    echo "  brev login                                    # interactive (opens browser)"
