How we got this
Bosonai is the maker of Higgs-TTS-3. We look at the gaps between its earlier versions (Higgs-TTS-3, 2026-06-04) and project the next one. It is a guess from a pattern, not news: the maker has not said Higgs-TTS-3.1 exists. This page turns into the launch page, with price and facts, as soon as the model shows up on OpenRouter, Hugging Face or GitHub.
