OpenAI 在 API 中推出 GPT-Realtime-2 和翻譯功能
openai 在其 realtime api 中增加了三個新語音模型：gpt-realtime-2 採用 gpt-5 級推理能力，gpt-realtime-translate 支援超過 70 種輸入語言，gpt-realtime-whisper 提供即時語音轉文字功能。這些模型針對客戶服務和教育用例，並包含防止濫用和詐欺的防護措施。
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.
