# ChatGPT语音模式使用GPT-4o早期版本模型

开发者发现ChatGPT语音模式实际运行的是GPT-4o的早期版本，知识截止日期为2024年4月，弱于当前文本交互使用的模型。这表明OpenAI可能在语音服务上采用性能优化策略，而非使用最新模型。用户需注意语音输出的知识局限性。

## English Version

**ChatGPT Voice Mode Uses Older GPT-4o Model**

Developers reveal ChatGPT's voice mode runs on an older GPT-4o version with a knowledge cutoff of April 2024, weaker than the text model. This suggests OpenAI may prioritize performance optimization over using the latest model for voice interactions. Users should note the knowledge limitations in voice responses.
