OpenAI最快模型GPT-5.3-Codex-Spark发布仅7个月即下周退役。它每秒1200 token，是首个脱离英伟达、由Cerebras 750兆瓦大单交付的模型，但用量持续下滑，且已有更优替代。负责人称需为未来让路，并吐槽模型名过长。
OpenAI与Cerebras合作推出GPT-5.3-Codex-Spark模型，专为实时编程优化，解决AI编程中的“等待焦虑”。该模型利用Cerebras晶圆级引擎实现超高速推理，速度突破1000tokens/s，实现代码生成与思绪同步的即时反馈。
OpenAI加速推进“去英伟达化”战略，于2026年2月12日发布首款基于Cerebras芯片的AI模型GPT-5.3-Codex-Spark。该模型专为软件工程师设计，提供更灵活的交互体验，支持即时中断与切换，使开发者能随时暂停冗长计算，快速处理其他紧急编码任务。
