We measured Gradium TTS Beta on our TTS board: 49ms p50, 56ms p90 time to first audio from US East.
That is more than 4x faster than the previous Gradium TTS (217ms p50), with the same naturalness.
Full results: benchmarks.speko.ai/tts
Gradium TTS beta model is out now to define what fast means.
Less than 50ms TTFA, same quality. Most models are >100ms TTFA.

I've always wanted a way to talk to my Mac and do things on the go.
Until now, it was super slow.
So I built Macbrow.
Voice-controlled browser and computer-use agent.
Built using @GradiumAI @browser_use and @typesafeai
Still early and a work in progress.
