OpenAI 推出了两款新的 Realtime 模型 GPT-Realtime-2.1 和 GPT-Realtime-2.1-mini，通过其 API 为低延迟语音和多模态应用而设计。GPT-Realtime-2.1-mini 是一款更小、更具成本效益的推理模型，用于实时语音交互，在保持先前定价的同时，增强了推理和工具使用能力。OpenAI 还宣布，通过改进的缓存机制，其所有 Realtime 语音模型的 p95 延迟显著降低了至少 25%。 AI
影响 通过改进的延迟和推理能力增强了实时语音代理的功能，可能加速在客户支持和交互式应用中的采用。

<p>OpenAI added two Realtime models to its API. GPT-Realtime-2.1-mini is a mini reasoning model for voice, priced like the earlier gpt-realtime-mini. OpenAI also cut p95 latency by at least 25% through improved caching. Here is what changed, how pricing compares, and how to conne…
OpenAI has released GPT-Realtime-2.1-mini, a compact reasoning model for voice interactions. It keeps the earlier mini pricing while adding reasoning, and OpenAI cut p95 latency by at least 25 percent through improved caching. https://www. marktechpost.com/2026/07/06/op enai-gpt-…
