TTS startup Gradium opened its beta: time-to-first-audio (TTFA) under 50ms—most models exceed 100ms—with no quality tradeoff, per the company. A booster post adds this isn't a limited "Flash" variant but their most accurate and expressive model yet, with "many releases coming soon." Robotics researcher Rémi Cadene amplified the announcement.
