Q: Can MOSS-TTS run locally?

MOSS-TTS is listed by LocalClaw as a local TTS option. Hardware fit depends on runtime, model size and backend support.

Catalogue summary: Canonical OpenMOSS full speech generation family with 8B and 1.7B checkpoints for multilingual zero-shot voice cloning, emotion control and long-text generation. Heavier than Nano, but materially better for production-quality local voice work.
