# ── Tahkik Inference Space ──────────────────────────────────────────────────
# Uses faster-whisper (CTranslate2 INT8) for ~4x faster inference vs PyTorch.
# To enable GPU (T4/L4/A100), change the base image to:
#   FROM nvidia/cuda:12.1-runtime-ubuntu22.04
# and set compute_type="float16" in main.py.
