## Choose when

### Choose GPT-SoVITS if…

- GPT-SoVITS is primarily Python; PROMPTPurify is TypeScript.
- Tags unique to GPT-SoVITS: python, text-to-speech, tts, vits.
- Also covers Speech & Audio.
- GPT-SoVITS ships Docker support for self-hosted deployment.

### Choose PROMPTPurify if…

- PROMPTPurify is primarily TypeScript; GPT-SoVITS is Python.
- Tags unique to PROMPTPurify: ai-firewall, ai-safety, ai-security, application-security.
- Also covers LLM Frameworks.

## When NOT to use GPT-SoVITS

- Model Training: Try prompting and RAG first; fine-tuning is the answer to style/format, not missing knowledge.

## When NOT to use PROMPTPurify

- 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.
