OpenAI 在 API 中推出 GPT-Realtime-2 和翻译功能
openai 在其 realtime api 中增加了三个新语音模型：gpt-realtime-2 采用 gpt-5 级推理能力，gpt-realtime-translate 支持超过 70 种输入语言，gpt-realtime-whisper 提供实时语音转文字功能。这些模型针对客户服务和教育用例，并包含防止滥用和欺诈的防护措施。
OpenAI expanded its Realtime API with three new voice intelligence models. GPT-Realtime-2 utilizes GPT-5-class reasoning to handle complex user requests, while GPT-Realtime-Translate supports over 70 input and 13 output languages. A third model, GPT-Realtime-Whisper, provides live speech-to-text transcription. These tools aim to shift interfaces from simple call-and-response to systems that can reason and act during conversations. The company implemented guardrails to prevent spam, fraud, and policy violations. Billing varies by model, with Translate and Whisper charged by the minute and GPT-Realtime-2 by token consumption.
