## When NOT to use Tacotron-2

- Last GitHub push was 1101 days ago (dormant maintenance, Jul 6, 2023). Validate activity before betting a new project on Tacotron-2.
- Model Training: Try prompting and RAG first; fine-tuning is the answer to style/format, not missing knowledge.
- Evaluation & Observability: Defer heavyweight eval infra only until you have real traffic - never skip it once users depend on answers.
