excited to announce the launch of gpt-live API. a few things to note: the novel architecture of the gpt-live model needed a new API, providing much more control to developers compared to previous speech-to-speech systems. we did specific training to further improve the controllability and instruction following of the model. it is offered at a very reasonable and competitive price of $0.05 per minute for the live model. generally, i think we are on a steep trajectory of improving cost, latency, and quality of realtime conversational models. this is our first API release toward that end with the new model series. we are investing actively and heavily to make this the best across our 1p products and provide maximum flexibility to developers via API. proud of the team for this release! please expect regular updates on this model series from now on!

In my ~14 months at @OpenAI, one of the most surprising and genuinely wonderful things about it, has been the full leadership support for full-duplex models (gpt-live series), even when it seemed deeply improbable that they would work. And yet, if they did work, it was obvious how magical they could be. I am quite sure this is not an exception but a general rule for research projects at @OpenAI. There were so many moments when the problem felt impossibly hard. But one thing kept being true: it was never clear why it shouldn’t work. And almost every time we understood the problem a little better, it became a little easier to solve. I’m pretty sure there are very few environments in the world where a bet like this could have been made and sustained. So grateful to be part of this wonderful place.
