- The novel architecture required a new API, giving developers far more control than previous speech-to-speech systems
- Specific training improved controllability and instruction following
- Priced at a competitive $0.05 per minute
He frames it as the first release in a new series on a steep trajectory of improving cost, latency, and quality, with regular updates to come.
