MOSS-TTS Nano TTS

A 100M-parameter MOSS-TTS variant — same delay-transformer family, ~80x smaller, tuned for free-tier latency.

MOSS-TTS Nano is OpenMOSS's compact 100-million-parameter sibling to the flagship MOSS-TTS, sharing the same delay-transformer architecture but roughly 80x smaller. It gives up the 8B model's peak quality in exchange for far lower per-request VRAM (~2GB) and fast ~2-second generation, which makes it well suited to free-tier and high-throughput deployments. It keeps broad multilingual reach across 11 languages and, unlike many lightweight models, still supports zero-shot voice cloning. The result is a budget-friendly option for high-volume or low-latency interactive use where speed and cost matter more than studio fidelity.
