# --timeout 120: bertweet-large is slow to load/infer on free CPU. The default
# gunicorn worker timeout (30s) can kill the worker during a cold start or a
# large review batch, which surfaces to the caller as a failed request (and to
# the leaderboard as a null). 120s gives the model room to load and respond.
