subtitles-ro on owned GPU
Production AI on our own GPU — a Romanian subtitle pipeline (Whisper + LLM) on an NVIDIA DGX Spark.
The problem
Accurate Romanian subtitles at scale need real ASR + LLM post-editing — costly and privacy-sensitive on cloud APIs.
Our approach
- End-to-end pipeline: Whisper + LLM correction on an owned DGX Spark (GB10 Blackwell, 128GB).
- Browser-based editor behind Traefik on our own hosting, plus a burn-in montage tool.
- Operate the AI on-prem — no per-token cloud bill, full data control.
