GPT-Live-1 is a voice model from OpenAI for full-duplex, real-time spoken conversation, available through its API. Recent coverage covers OpenAI adding it to the API in September 2026 with better instruction following, custom voices and telephony support, Amp using it among models to extend AI agents beyond coding, and Dessa releasing a competing full-duplex speech model trained only on human conversation audio.
Dessa launches full-duplex speech model trained only on human conversationDessa introduced Dessa, billed as the most authentic full-duplex speech model, trained from scratch only on human conversation audio without text or pretrained models. It converses in real time with emotion, pauses and natural cadence, laughing mid-sentence, raising volume, and finishing sentences, behaviors absent in text-based voice AI.
Amp puts AI agents to work beyond code with OpenAI modelsAmp pushes the frontier of what AI agents can do beyond coding, using GPT-6 Astra, Ultrafast, GPT-Live-1, and Sign in with ChatGPT.
OpenAI adds GPT‑Live‑1 voice to APIOpenAI released GPT‑Live‑1 for its API, enabling natural full‑duplex voice conversations with improved instruction following, custom voices, and telephony support to make voice experiences more lifelike.
