## Choose when

### Choose MARS5-TTS if…

- MARS5-TTS is primarily Jupyter Notebook; LocalAI is Go.
- License: MARS5-TTS is AGPL-3.0, LocalAI is MIT.
- Tags unique to MARS5-TTS: voice-cloning, prosody, voice-cloneai, text-to-speech.
- Also covers Inference & Serving.

### Choose LocalAI if…

- LocalAI is primarily Go; MARS5-TTS is Jupyter Notebook.
- License: LocalAI is MIT, MARS5-TTS is AGPL-3.0.
- Pricing: As an open-source project under the MIT license, it is free to use and distribute..
- Tags unique to LocalAI: image-generation, audio-generation, distributed, libp2p.
- Also covers LLM Frameworks.
- LocalAI ships Docker support for self-hosted deployment.
- Use LocalAI when you need model flexibility, as it can run different types of models (LLMs, computer vision, speech & audio) on any type of hardware.

## When NOT to use MARS5-TTS

- Last GitHub push was 709 days ago (dormant maintenance, Aug 1, 2024). Validate activity before betting a new project on MARS5-TTS.
- Inference & Serving: Self-hosting rarely beats a hosted API on cost until you have steady, high-volume traffic.

## When NOT to use LocalAI

- Avoid LocalAI if you need to leverage GPU-specific optimizations for performance acceleration as it promotes no-GPU usage, potentially sacrificing speed for accessibility.
- Do not use LocalAI where specific language runtime environments are required that do not align with Go (the language in which LocalAI is written).
