OpenAI launches GPT‑Live voice models
OpenAI introduced GPT‑Live, a new full‑duplex family of voice models powering ChatGPT Voice that can listen and speak simultaneously and delegate complex tasks to other models in the background. GPT‑Live (including GPT‑Live‑1 and GPT‑Live‑1 mini) adds live translation, visual answer cards and improved noise suppression; the mini version will be available to free ChatGPT users. OpenAI says GPT‑Live can hand off deeper analyses to larger models such as GPT‑5.5 (and an upcoming GPT‑5.6) and then return results into the ongoing conversation. The models are rolling out on ChatGPT for web, iOS and Android, with API access planned and developer registration open. The article references hands‑on testing by AI expert Jens Polomski and notes more than 150 million people already use ChatGPT’s voice/dictation features.
OpenAI (a major platform) released an advanced conversational voice model with full‑duplex capability and background model delegation; this materially affects conversational interfaces, voice UX adoption, developer integrations and potential voice‑driven discovery/ads.

OpenAI launches GPT‑Live real‑time voice system
OpenAI describes GPT‑Live, a full‑duplex realtime voice system that streams audio into a voice model capable of listening and speaking simultaneously, removing prior turn‑detector architectures. The system uses stateful, streaming inference and an asynchronous delegation path to consult larger frontier models (e.g., GPT‑5.5) without blocking the live media loop. Engineering changes include rewriting the media frontend and inference logic in Go, using WebRTC for transport, new handshake/transport optimizations (WARP and Instant Connect), and production shadow testing of real ChatGPT Voice sessions. The architecture separates the live media path from application logic, supports seamless model instance handoffs and context compaction, improves observability and rollout controls, and will underpin a forthcoming GPT‑Live API and expanded ChatGPT Voice capabilities.
OpenAI Launches GPT-Live-1 Voice Model in API
OpenAI has launched GPT-Live-1 in its API, a voice-native model designed for building voice-enabled applications and business workflows. The model handles listening and speaking simultaneously, reducing latency by eliminating the need for chained speech-to-text, reasoning, and text-to-speech components. It features improved interruption handling, background noise resilience, and the ability to delegate reasoning and tool calls to backend models like GPT-6 Astra or third-party models. The API includes telephony support for full-duplex voice agents. Pricing is set at $0.05 per minute for the voice layer, with backend models billed separately. Early evaluations show an 80% reduction in interruptions for language tutoring compared to turn-based systems.
OpenAI launches three Realtime voice models
OpenAI announced the addition of three realtime voice-intelligence models to its Realtime API on May 7, 2026: GPT‑Realtime‑2, a GPT‑5‑class reasoning voice model for realistic conversational and agentic workflows; GPT‑Realtime‑Translate, which provides live translation with support for more than 70 input languages and 13 output languages; and GPT‑Realtime‑Whisper, a low-latency streaming speech-to-text transcription capability. The features are intended for customer service, education, media, events and creator platforms. Translate and Whisper are billed by the minute while GPT‑Realtime‑2 is billed by token consumption. OpenAI said it has embedded safety guardrails and active classifiers to halt conversations that violate harmful-content policies. The announcement follows OpenAI’s published evaluations showing gains versus prior realtime models and details pricing and safety controls in the Realtime API documentation.
