作者 | 冬梅1 OpenAI 发布新模型，专为实时编码而生昨晚，OpenAI 正式发布了 GPT-5.3-Codex-Spark 的研究预览版本。这是一款从 GPT-5.3-Codex 主模型中“裁剪”而来的精简版本，同时也是 OpenAI 首个 专门围绕实时编码（real-time coding）场景设计的模型。从定位上看，Codex-Spark 并不是为了替代现有的 Codex，而是补齐其.

在具体能力方面，OpenAI 强调 Codex-Spark 擅长进行精确代码修改、计划调整，并能围绕代码库进行上下文问答。官方还提到，该模型适用于快速可视化新布局、优化样式，以及测试新的界面变更等工作。
