# Nightly per-GPU voice-bench smoke run.
#
# STATUS: stub. Gated by workflow_dispatch input until a self-hosted CUDA GPU
# runner is wired. L4 (the cheapest GitHub-hosted GPU runner) is a reasonable
# starting target; for the full matrix (3090 / 4090 / 5090 / H200) we
# need a self-hosted pool.
#
# Per docs/inference/gpu-tier.md the per-GPU autotune profiles live in
# packages/inference/configs/gpu/, and `voice-bench bench gpu` prints
# the resolved plan for the host card. Once a real cuda PipelineDriver
# is wired (see packages/inference/voice-bench/README.md "Wiring the
# real pipeline"), this workflow runs the actual benchmark.
