xAI发布新一代语音模型Grok Voice Think Fast 2.0，全面向开发者开放，在智能水平、转录精度、对话交互和工具调用效率上显著提升。定价每分钟0.08美元，在Artificial Analysis基准测试中综合得分为82.9%，超越前代及GPT-Realtime-2.1、Gemini 3.1 Flash。
OpenAI推出基于GPT-Live架构的全新ChatGPT语音体验，告别传统语音系统，专为智能语音代理打造实时音频模型。此前已公开的GPT-Realtime-2将GPT-5级推理引入实时交互，能更稳定地处理复杂请求，实现语音技术架构跃迁。
OpenAI推出三款实时语音模型：GPT-Realtime-2、GPT-Realtime-Translate和GPT-Realtime-Whisper，集成至Realtime API。GPT-Realtime-2是首个最智能的AI语音模型，旨在解决语音交互中的延迟高、无法自然打断和多语言支持难等痛点。
