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 vall-e - - Avoid VALL-E if your project does not align with the specific requirements, such as the exact version of Python (Python 3.10.7) it was tested on. - - Do not use this tool if you lack a GPU that is compatible and tested by DeepSpeed or do not have access to CUDA or ROCm compilers. ## Common questions ### What is the difference between MockingBird and vall-e?
