About
GPT-Live-1.1 is OpenAI’s full-duplex voice model for real-time conversational use in ChatGPT Voice. It listens and speaks continuously, so it can follow pauses, interruptions, and shifts in speaking pace rather than waiting for a clearly completed turn. In ChatGPT, Live conversations can combine voice with text and images, and may use web search, memory, and connected apps according to the account, plan, and workspace settings. Access is provided through ChatGPT experiences on the web and supported mobile apps, with availability and usage limits determined by plan. The model is intended for individuals and organizations that want spoken assistance for questions, brainstorming, information lookup, and everyday tasks. GPT-Live-1.1 succeeds GPT-Live-1 in OpenAI’s voice-model family.

About
StepAudio 3 is StepFun’s next-generation audio model family, built to understand, generate, and interact through voice, sound, and music. The lineup includes StepAudio 3 Realtime for natural full-duplex conversation, StepAudio 3 ASR for speech recognition, StepAudio 3 TTS for speech synthesis, StepAudio 3 Gen for general-purpose audio generation, and StepAudio 3 Music for long-form music creation. Realtime is designed around a continuous listen-converse-think-act loop, understanding not only words but also hesitation, laughter, emotion, pauses, backchannels, and interruptions. It can think while speaking, reason through harder questions without breaking conversational flow, and use tools to complete tasks once it understands the user’s intent. StepAudio 3 Gen unifies zero-shot TTS, voice design, vocal generation, sound effects, music, and mixed audio generation within one framework, while StepAudio 3 Music supports text-controlled songs, instrumentals, vocal arrangement, and more.
