## Choose when

### Choose ChatTTS_colab if…

- ChatTTS_colab is primarily Python; MARS5-TTS is Jupyter Notebook.
- Tags unique to ChatTTS_colab: chattts, colab-notebook.
- When you want a simplified setup with minimal configuration needed in a browser-based environment using Google Colab.

### Choose MARS5-TTS if…

- MARS5-TTS is primarily Jupyter Notebook; ChatTTS_colab is Python.
- Pricing: Open-source version is free for non-commercial use; commercial licenses are available upon request by contacting help@camb.ai..
- Requirements: Supports custom development through Docker, allowing you to build a base image and extend with your own inference scripts.; Docker integration provides flexibility but requires users to have the necessary environment setup for usage..
- Tags unique to MARS5-TTS: docker-support, jupyter-notebook, prosody, speech-synthesis.
- When you have projects requiring nuanced prosody control for more natural sounding synthesized speech, as MARS5-TTS is specifically highlighted for its prosodic synthesis abilities.

## When NOT to use ChatTTS_colab

- If your project needs do not include the ability to generate audio on-the-fly or manage multiple character readings.
- When you want to avoid Colab's resource limitations that could affect performance for heavy text-to-speech tasks.
- In scenarios where offline package support is not necessary, as this might introduce unnecessary complexities.

## When NOT to use MARS5-TTS

- When you require immediate access to pre-built output-generating Docker images, since as of now these are not yet available despite plans for their future addition.
- If your project needs a model that does not involve the GNU AGPL-3.0 license, because this might impose restrictions on how derivative works can be distributed.
