We released Sonic-3.5 and Ink-2, the #1 streaming models for text to speech and speech to text you can use in your voice agents today. New architectures enable new frontiers for speed and quality. We're now the only provider to have #1 models for both speaking and listening.

You shouldn't have to trade speed for quality. With our new ASR and TTTS models, you don't. Ink-2 (ASR) and Sonic-3.5 (TTS) just debuted at #1 on their respective leaderboards across both accuracy and latency. Try them out!

Pumped to see what people build with this!
