Description

OpenAI's GPT-Live-1.1 serves as a full-duplex voice model designed for real-time interactions within ChatGPT Voice. This model adeptly listens and speaks in an ongoing manner, allowing it to accommodate pauses, interruptions, and variations in speaking speed instead of waiting for a turn to be clearly finished. In the ChatGPT environment, live discussions can seamlessly integrate voice with text and images, while also utilizing web searches, memory features, and connected applications based on specific account, plan, and workspace configurations. Users can access this capability through ChatGPT on the web and via compatible mobile applications, with the scope of availability and usage constraints governed by the chosen plan. The model is specifically crafted for both individuals and organizations seeking vocal support for inquiries, brainstorming sessions, information retrieval, and daily tasks. GPT-Live-1.1 represents an advancement over its predecessor, GPT-Live-1, within OpenAI's lineup of voice models, aiming to enhance user interaction and engagement. This innovation exemplifies a commitment to improving conversational experiences in technology.

Description

GPT-Realtime-2.1 is an OpenAI realtime model designed for advanced voice-agent and speech-to-speech AI applications. It improves on GPT-Realtime-2 with stronger alphanumeric recognition, better silence and noise handling, and more natural interruption behavior. The model supports text, audio, and image inputs, while producing text and audio outputs for interactive realtime experiences. Developers can use GPT-Realtime-2.1 across endpoints such as Chat Completions, Responses, Realtime, realtime translation, realtime transcription sessions, and related OpenAI API workflows. The model supports function calling, configurable reasoning effort, instruction following, and reasoning token support for complex voice-agent tasks. Its 128,000-token context window and 32,000-token maximum output make it suitable for longer conversations and more detailed realtime workflows. GPT-Realtime-2.1 does not support video, structured outputs, fine-tuning, or predicted outputs according to OpenAI’s current documentation. Pricing starts at $4 per 1 million text input tokens and $24 per 1 million text output tokens, with separate pricing for audio and image tokens. By combining realtime audio interaction, reasoning, tool use, and multimodal input, GPT-Realtime-2.1 helps developers build responsive AI agents for support, sales, operations, translation, transcription, and interactive voice applications.
