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
Phonic is a real-time conversational AI platform designed to help organizations develop intelligent voice agents for customer service, recruiting, healthcare, logistics, and other business workflows. Its proprietary Phonic-1 model uses a native speech-to-speech architecture that processes audio directly instead of combining separate speech recognition, language generation, and speech synthesis services. This approach allows AI agents to recognize vocal tone, pauses, hesitation, and other conversational signals when responding to callers. The platform supports natural turn-taking, interruption handling, and conversations across more than 50 languages while maintaining a consistent voice. Phonic-1 provides response latency of approximately 600 milliseconds and can initiate external tool calls before a caller finishes speaking. Developers can connect agents to business applications, internal APIs, webhooks, and Model Context Protocol servers to retrieve information and execute authorized actions. The platform provides a no-code agent builder, REST APIs, Python and TypeScript SDKs, and command-line tools for creating and deploying voice applications. Supported use cases include candidate screening, appointment management, patient intake, customer support, order modifications, and dispatch coordination. Phonic offers conversation analytics, evaluation tools, SOC 2 Type II certification, HIPAA support with a business associate agreement, and deployment options ranging from managed cloud infrastructure to dedicated and self-hosted environments.
