OpenAI 将 Codex 模型上下文大小从 372k 缩减至 272k

OpenAI 悄然将 Codex 模型的可用上下文大小从 372k 缩减到 272k，用户发现早期频繁出现的“模型上下文大小超限”错误已不再出现。随着上下文缩减，OpenAI 开始采用类似加密子代理日志的方式隐藏会话细节，引发部分高级用户对透明度和可控性的担忧。

It’s fairly obvious that gate keeping models will not work at scale. Competing in AI is too economically and strategically important for China at this point, and we’ve now crossed the rubicon where it’s clear that the…

美国云服务商Box CEO Aaron Levie 和知名投资人 David Sacks 公开指出，试图通过封锁或限制模型来阻止中国 AI 进步的做法已行不通，因为中国 AI 在极短时间内追上了前沿水平。他们认为，美国应以更快的开放、更强的基建和更安全的扩散来保持全球竞争力，而非依赖“造围墙”。

Anthropic 宣布其新模型 Claude Fable 5 将于 2026 年 7 月 20 日纳入 Max 和 Team Premium 计划，并以 50% 配额形式提供。由于需求激增和交付压力，内部团队曾“几乎昼夜不休”地赶工完成上线。

一位父亲与8岁女儿共同使用ChatGPT的“ChatGPT Sites”功能，创建了一个乘法表学习网站，全程不写代码，仅靠对话式AI完成UI设计、角色生成和游戏机制开发。这一案例展示了ChatGPT从“对话工具”向“应用生产平台”的进化，以及对非技术用户的普及意义。

Zara Zhang 在 X 上提出，每个人都应为 AI 模型开发自己的“个人评估集”——一组与日常工作生活真正相关的任务，而非仅依赖行业基准。这一观点强调，用户通过主动测试模型边界，才能发现其实际可用性，而非盲目相信排行榜。
