Description
Amazon Nova Sonic is an advanced speech-to-speech model that offers real-time, lifelike voice interactions while maintaining exceptional price efficiency. By integrating speech comprehension and generation into one cohesive model, it allows developers to craft engaging and fluid conversational AI solutions with minimal delay. This system fine-tunes its replies by analyzing the prosody of the input speech, including elements like rhythm and tone, which leads to more authentic conversations. Additionally, Nova Sonic features function calling and agentic workflows that facilitate interactions with external services and APIs, utilizing knowledge grounding with enterprise data through Retrieval-Augmented Generation (RAG). Its powerful speech understanding capabilities encompass both American and British English across a variety of speaking styles and acoustic environments, with plans to incorporate more languages in the near future. Notably, Nova Sonic manages interruptions from users seamlessly while preserving the context of the conversation, demonstrating its resilience against background noise interference and enhancing the overall user experience. This technology represents a significant leap forward in conversational AI, ensuring that interactions are not only efficient but also genuinely engaging.
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.
