从定位上看，Codex-Spark 并不是为了替代现有的 Codex，而是补齐其在"即时交互"场景中的短板：在过去，Codex 更擅长长时间运行的复杂任务，而 Codex-Spark 的目标则非常明确——把人与模型之间的交互延迟压缩到接近"无感"的程度。 这一发布同时也是 OpenAI 与 芯片初创企业 Cerebras 合作的重要阶段性成果。为了减少对英伟达芯片的依赖，上个月 OpenAI 签署了一项金额超过 100 亿 美元的协议，使用 Cerebras 的硬件以提升其模型的响应速度，而 Codex-Spark 被视为这项合作落地的第一个技术里程碑。 为实时而生：Codex-Spark 的核心是"速度" 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。 在官方定义中，Codex-Spark 是一个"专为实时使用 Codex 而设计的模型"，它支持进行针对性编辑、 ...
