GPT-Live-1 Cuts Interruptions by Nearly 80% in Voice AI
GPT‑Live‑1 in the API
OpenAI has launched GPT-Live-1 in the API, a full-duplex voice model that listens and speaks simultaneously, eliminating the latency of chained speech-to-text, LLM, and text-to-speech pipelines. It handles interruptions, delegates deep reasoning to backend models like GPT-6 Astra, and supports telephony and silent context management. Early customer Speak saw interruptions drop by almost 80%. Priced at $0.05 per minute, it is available now.
In early evaluations, Speak found that GPT-Live-1 gave learners more time to think before the language tutor responded, cutting interruptions by almost 80% versus previous turn-based systems.

I've been waiting for this! I'm learning Spanish so I built an app to teach me Spanish, but hyperfocused on scenarios in my life, for example "watching a Barça match in a Barcelona bar". It does FSRS flashcard training, and live conversation practice.
I think education is a very underexplored area for these live conversation models. Yes you can just use ChatGPT Live but that's freeform and unstructured, doesn't have a curriculum or can present supporting visuals, etc. On a grand scale if you can give children their own personal individual tutor rather than relying on group teaching alone, there could be a huge jump in successful education outcomes.

Congrats on the launch here. I've been messing with this over the last few hours- super super cool. I was excitedly awaiting this hitting the API, because ofc there wasn't a super high fidelity option for drop-in voice interface in front of a given harness. This is blowing me away so far!
(Side q, is there a single place one can watch for updates on the API- that actually covers everything that changes? IIRC there have been a couple of additions that you've tweeted- but never hit the API changelog ;] )

Even as someone really AI-forwards, there are just not enough selling points for me here. I almost never want to talk to an AI. I just don’t believe I’ll have a useful voice interaction. Maybe agents are here to fix that, but theres 30 years of really negative precedent from robot telephone bots to overcome, and I don’t think some new API is going to change that overnight

I think that this could be useful for the case of learning something by teaching it to someone else, and this someone else being the AI. We all know that learning-by-teaching is a great way to see the gaps in your knowledge and check whether you can explain the topic simple enough for the "student" to understand it. But finding the "student" is the hard thing in this process. Replacing the student with this model, and maybe a better reasoning model behind, sounds like a good enough replacement of a real person, for this case.

Been wanting to try this out on top of https://github.com/TristanBrotherton/voicepe-realtime with the HomeAssistant VoicePE
Anyone else hack something together with HA / the Voice PE yet?
Looks like it needs a second model to do function calling, which gpt-realtime-2.5 didn't, and the Voice PE XMOS chip's audio pipeline might not be a great fit for full duplex back and forth, like what gpt-live-1 now supports.
