# Local image tag — bump when you change Dockerfile or server.py to
# force a fresh build.

# Which Stable Audio model to load. As of 2026-04 the only released
# checkpoint is 1.0; future revisions can swap here without touching
# compose.yaml or server.py.

# ── network ──────────────────────────────────────────────────────────
# Host port (container listens on 8000 internally).
# Reservations on irv-ml1: 8188 ComfyUI, 8190 CosyVoice, 8191 Qwen3-TTS,
# 8192 IndexTTS-2, 8193 Kokoro, 8194 VibeVoice, 8195 Fish, 8196

# ── runtime / GPU ────────────────────────────────────────────────────
# GPU pinning. "0" = RTX 3090 (24 GB), "1" = RTX A6000 (48 GB).
# A6000 (1) recommended — Fish s2-pro lives there at ~17 GB; SAO adds
# ~6 GB practical (model fp16 + small VAE working set), and ACE-Step
# adds another ~12 GB during inference. Total ~35 GB / 48 GB still
# leaves headroom. The 3090 is full with the TTS slate.

#      and accept the Stability AI Community License (one click).
#   2. Generate a read token at
#      https://huggingface.co/settings/tokens.

# Without this, the first model download 401s and the container
# crashloops.

# HF cache — first start pulls the model (~6 GB) into this dir.
# Persistent across container recreates so we don't re-pull.

# Generated audio output — clients can pull from here for any flow
