Description

Visualize call patterns and categorize outcomes, key performance indicators, and more. Illustrate both frequent and rare conversation pathways while identifying calls that satisfy particular criteria. You can also incorporate personalized metrics to monitor what is most significant for the efficiency of your voice AI agent. One essential measure in voice AI is the Signal-to-Noise Ratio (SNR), which evaluates the clarity of the desired audio signal against the surrounding noise. A higher SNR signifies clearer sound quality, whereas a lower SNR indicates greater interference. Enhanced SNR alongside improved audio quality can significantly elevate the accuracy of automatic speech recognition and natural language processing. When audio is clearer, your Voice AI agent is better equipped to comprehend user input, thereby increasing the likelihood of successful calls. It is important to keep an eye on SNR to make real-time adjustments in audio signal processing for peak performance. Additionally, Voice AI Latency, which refers to the time lag between user input and the AI's reply, plays a vital role in facilitating effective conversations. Quick, responsive exchanges are essential for achieving successful interactions and enhancing the overall user experience.

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.
