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.
Description
The Gemini Live API is an advanced preview feature designed to facilitate low-latency, bidirectional interactions through voice and video with the Gemini system. This innovation allows users to engage in conversations that feel natural and human-like, while also enabling them to interrupt the model's responses via voice commands. In addition to handling text inputs, the model is capable of processing audio and video, yielding both text and audio outputs. Recent enhancements include the introduction of two new voice options and support for 30 additional languages, along with the ability to configure the output language as needed. Furthermore, users can adjust image resolution settings (66/256 tokens), decide on turn coverage (whether to send all inputs continuously or only during user speech), and customize interruption preferences. Additional features encompass voice activity detection, new client events for signaling the end of a turn, token count tracking, and a client event for marking the end of the stream. The system also supports text streaming, along with configurable session resumption that retains session data on the server for up to 24 hours, and the capability for extended sessions utilizing a sliding context window for better conversation continuity. Overall, Gemini Live API enhances interaction quality, making it more versatile and user-friendly.
