# Scriberr — self-hosted audio/video transcription with speaker diarization.
# Upstream: https://github.com/rishikanthc/Scriberr  (Go + SvelteKit, SQLite).
#
# Transcription runs locally via WhisperX (Whisper + pyannote diarization);
# NVIDIA Parakeet / Canary models are also selectable in the UI. Optional
# summarisation / transcript chat talks to any OpenAI-compatible endpoint —
# point it at the LiteLLM gateway rather than a paid API (see README).
#
# ── IMAGE: BUILT LOCALLY, ON PURPOSE ──────────────────────────────────────
# fv-ml1's RTX PRO 6000 Blackwell cards are **sm_120**. Upstream publishes
# `scriberr-cuda` (built for sm_61…sm_89 — no sm_120 kernels) and documents a
# `scriberr-cuda-blackwell` image that **has never actually been published**
# (GHCR returns no tags for it, checked 2026-08-23). The sm_120 path upstream
# ships is `Dockerfile.cuda.12.9` (CUDA 12.9.1 + cu128 torch), built locally.
# Do NOT "simplify" this to the published `scriberr-cuda` image — it will
# fail on these cards or silently fall back to CPU.
#   Rebuild: see README "Rebuilding" — checkout lives at
#   /tank/scriberr/src/Scriberr on fv-ml1.
#
# ── GPU PINNING ───────────────────────────────────────────────────────────
# Pinned to **GPU1** via explicit device_ids, per the house convention and
# because GPU0 is fully committed to the `gen` seat. GPU1 shares space with
# the `sec` seat, so this stack is a guest there — keep an eye on VRAM.
# NOTE: do NOT add `NVIDIA_VISIBLE_DEVICES=all` (as upstream's compose does).
# It overrides the device_ids reservation and exposes both cards.
#
# All tunables live in .env — edit that, not this file.
