深度参与自身开发！GPT-5.3 Codex正式发布，速度提升25%,编程,codex,gpt ...

GPT-5.3-Codex在多个方面实现了显著突破。根据OpenAI公布的信息，新模型运行速度较前代提升25%，任务执行时长大幅延长，甚至能够处理需要持续运行超过24小时的复杂进程。在测试阶段，研究人员利用该模型开发了两款网络游戏，通过数百万个Token的连续处理，成功完成了整个开发流程。这一特性使得开发者能够更高效地完成大型项目，减少了任务中断带来的效率损失。

OpenAI周四发布GPT-5.3-Codex。该公司称，这是迄今为止能力最强的编程代理。值得注意的是，此次发布的时间点被精准安排在Anthropic推出其旗舰模型升级版Claude Opus 4.6的同一时刻。媒体称，两大模型同步亮相，被业内观察人士视为“AI编程大战”的第一枪——这是一场围绕企业级软件开发市场展开的高风险争夺战。
