OpenAI 报告称，其专用的 Codex Mac 应用在上线后略多于 1 周即突破 1000000 次下载；同时，在 GPT-5.3-Codex 发布后，Codex 的总用户数按周成长 60%。Sam Altman 表示，初期推广结束后，Codex 仍将提供给 Free 与 Go 用户使用，这显示出即使需求快速增长，该公司仍采取广泛开放的策略。

"近年来，GPT-5.3等大型语言模型通过引入更复杂的架构和优化算法，极大提升了上下文推理和多轮对话的表现。这使得这些模型在机器翻译、文本摘要等任务中得到广泛应用。",

OpenAI 也新增了工作流程控制，让使用者可依专案指定特定网站与已连接的应用程式，并且可在生成过程中编辑范围或来源，而不必等到完成后才处理。Deep Research 的变更已立即释出给 Plus 与 Pro 使用者，Free 与 Go 预计稍后推出；日期为 February 10 的发布说明确认了此次推送，且 GPT-5.2 也获得了较小幅度的调校更新，以提供更审慎且更有根据的回应，显示采用扩张与治理限制两者正在并行扩展。

OpenAI reported that its dedicated Codex Mac app passed 1000000 downloads a little over 1 week after launch, while total Codex users rose 60% week over week after the GPT-5.3-Codex release. Sam Altman said Codex will remain available to Free and Go users after the initial promotion, signaling a broad-access strategy despite rapid demand growth.

At the same time, OpenAI warned that Free and Go tiers may face tighter usage caps than higher-paid plans, even as access remains free. Deep Research received a substantial product update: a full-screen report viewer separated from chat, a left-side table of contents with links and anchors, a right-side source panel for verification, and export options to PDF and Word for offline review and editing. (Key numbers: 5.3)

OpenAI also added workflow controls that let users target specific websites and connected apps per project and edit scope or sources during generation instead of waiting for completion. The Deep Research changes were released immediately to Plus and Pro users, with Free and Go expected later; release notes dated February 10 confirmed the rollout, and GPT-5.2 also received a smaller tuning update for more measured, grounded responses, indicating parallel scaling of both adoption and governance constraints.
