## Choose when

### Choose airunner if…

- License: airunner is GPL-3.0, GPT-SoVITS is MIT.
- Tags unique to airunner: ai-art, chatbot, deep-learning, image-generation.
- Also covers Evaluation & Observability, Inference & Serving.

### Choose GPT-SoVITS if…

- License: GPT-SoVITS is MIT, airunner is GPL-3.0.
- Tags unique to GPT-SoVITS: python, text-to-speech, tts, vits.
