Validate activity before betting a new project on bark. - LLM Frameworks: Avoid a framework for a single prompt-and-retrieve call; the abstraction can cost more than it saves. - Model Training: Try prompting and RAG first; fine-tuning is the answer to style/format, not missing knowledge. - Inference & Serving: Self-hosting rarely beats a hosted API on cost until you have steady, high-volume traffic. ## When NOT to use TensorFlowTTS - Last GitHub push was 737 days ago (dormant maintenance, Jul 5, 2024). Validate activity before betting a new project on TensorFlowTTS. - 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 bark and TensorFlowTTS? bark: 🔊 Text-Prompted Generative Audio Model.
