About

GPT-Realtime-2 is OpenAI’s voice model for live interactions where the model can keep the conversation moving while it reasons through requests, calls tools, handles corrections or interruptions, and responds in a way that fits the moment. It is built for a new class of voice apps that feel more natural, respond more intelligently, and take action in real time. GPT-Realtime-2 brings GPT-5-class reasoning to voice experiences, helping agents understand what someone means, track context, recover when a request changes, use tools while the conversation continues, and carry the conversation forward naturally. Developers can enable short preambles like “let me check that” so users know the agent is working, and the model can call multiple tools at once while making actions audible with phrases like “checking your calendar” or “looking that up now.” It also has stronger recovery behavior, longer context for agentic workflows, better retention of specialized terminology, etc.

About

Higgs Realtime is a production-quality, real-time speech-to-speech model and API built for natural, continuous conversation. It is an end-to-end, instruction-tuned, audio-native model that can understand audio, text, or both and generate high-quality responses, while also functioning as a text LLM when given text alone. Designed for live voice agents, it follows conversations, handles interruptions, adapts when requests change mid-sentence, and carries multi-step workflows through to completion. The model is trained specifically for voice-agent reflexes such as natural turn-taking, conversational cadence, tone adaptation, spoken tool preambles, multi-turn state tracking, and robust instruction following through changing requests. Semantic turn detection helps distinguish a completed turn from a pause, while multilingual and code-switched understanding supports more than 100 languages without per-language setup.
