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。
OpenAI正式向全球开发者开放GPT-5.3-Codex编程大模型。该模型融合了GPT-5.2-Codex的编码效率与GPT-5.2的通用推理能力，不再局限于代码生成，成为功能更全面的智能编程工具。用户可通过官方API或第三方平台直接调用。
