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。
平台宣布将于2026年6月2日强制下线GPT-5.2、GPT-5.3-Codex等多款旧版大语言模型，全面推行旗舰模型GPT-5.5。此举引发开发者群体争议，因新版模型在实际应用中存在明显性能下降问题，开发者公开抱怨并反弹。
OpenAI工程师意外在代码仓库中泄露了尚未发布的“gpt-5.4”型号信息，引发技术圈震动。尽管公司迅速修正为“gpt-5.3-codex”，但多方认为这并非简单失误，暗示大模型领域可能迎来重大更新。
OpenAI最强编程模型GPT-5.3-Codex全面开放，AI辅助开发进入新阶段。该模型不仅能生成代码，更能深度理解工程脉络，实现从“写代码”到“懂工程”的跨越，标志着开发者生产力工具的史诗级强化。
