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
Griffin serves as Tavus’s inaugural Human Interaction Model, a sophisticated full-duplex video-to-video system crafted to comprehend and produce real-time face-to-face human interactions. In contrast to conventional conversational systems that tackle speech recognition, language modeling, and speech synthesis in a linear manner, Griffin operates by continuously absorbing audio and video inputs, making instantaneous decisions about responses, and concurrently delivering expressive speech and visual output. It carefully considers not just the spoken words but also the subtleties of tone, eye contact, facial expressions, gestures, pauses, interruptions, and the broader visual environment. The model is capable of backchanneling, yielding or taking conversational turns, effectively responding to interruptions, maintaining engagement during moments of silence, and adapting its emotional tone and nonverbal cues as the dialogue evolves. Moreover, Griffin is adept at generating a comprehensive visual scene from a reference image, capturing elements like the face, body, hands, chair movements, shadows, and background, which allows it to present more than just a talking head in conversation. This advanced functionality enhances the overall authenticity and richness of human-like interaction.
