## Choose when

### Choose flower if…

- License: flower is Apache-2.0, GPT-SoVITS is MIT.
- Tags unique to flower: ai, android, artificial-intelligence, cpp.
- Also covers LLM Frameworks.

### Choose GPT-SoVITS if…

- License: GPT-SoVITS is MIT, flower is Apache-2.0.
- Tags unique to GPT-SoVITS: python, text-to-speech, tts, vits.
- Also covers Speech & Audio.

## When NOT to use flower

- 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.
