Validate activity before betting a new project on MockingBird. - Inference & Serving: Self-hosting rarely beats a hosted API on cost until you have steady, high-volume traffic. - Model Training: Try prompting and RAG first; fine-tuning is the answer to style/format, not missing knowledge. ## When NOT to use TensorFlowASR - Last GitHub push was 395 days ago (dormant maintenance, Jun 11, 2025). Validate activity before betting a new project on TensorFlowASR. - Model Training: Try prompting and RAG first; fine-tuning is the answer to style/format, not missing knowledge. ## Common questions ### What is the difference between MockingBird and TensorFlowASR?
