    Hugging Face 发布 2026 夏季开源模型观察:Qwen 衍生模型达 15 万个

    Claude Dispatch 与界面之争:为什么聊天窗口不是用 AI 干活的正确方式

    好的界面是什么样子? 一种选择是为特定工作或任务构建专门的界面。在所有专门的 AI 界面中,真正完整的只有编程类界面。这完全在预料之中:AI 实验室的员工是程序员,模型在代码上接受了大量训练,而构建这些工具的人往往是为自己而建。 我之前写过 Claude Code,这是 Anthropic 的编程智能体,可以自主工作数小时。OpenAI 的 Codex 和 Google 的 Antigravity 也能做类似的事情。我用 Claude Code 做过各种事情,从赚(少量)钱到做游戏,完全没碰过任何代码。我也发现 Codex 极其有用,能力水平相近。这些工具非常出色,但它们确实是为程序员打造的。它们假定你懂 Python 和 Git。它们的界面看起来像 1980 年代的计算机实验室。对于并非开发者的 99% 知识工作者来说,这些强大的 AI 工具并没有为他们优化。 Pomelli、Stitch 和 NotebookLM 在所有 AI 实验室中,Google 似乎在为其他职业构建专门界面方面试验得最多。它们都还有些粗糙,但展示了当 AI 工具为其他类型的知识专业人士构建时,未来可能是什么样
