What MOSS-TTS (8B) needs to run
MOSS-TTS is the 8-billion-parameter flagship in the MOSS speech family. Its model size, memory requirements, and lack of a browser export make it a server deployment rather than an on-device option. Use MOSS-TTS-Nano here for the browser-oriented member of the family.
Separate server setup required
This model is too large for the current browser runtimes and does not have a working browser export. For a model from the same family that is designed for browser use, try MOSS-TTS-Nano. The full model requires a separate server-class installation.
