OpenAI’s London DevDay—Romain Huet demonstrated a live drone setup in under 2 minutes using o1, along with a London Tube app built on stage. 

The audience gained full o1 access, including updated Realtime API pricing with caching: 50% off cached text inputs and 80% off cached audio. The Realtime API now offers five expressive voices—Coral, Verse, Ballad, Sage, and Ash—supporting new speech-to-speech capabilities with steerable vocal tones.
