An engineer’s notebook
Hi, I’m Levi, a developer from China.
I want to write something on the road of building.
Using Claude Fable 5 convinced me that AI has crossed a capability threshold. Falling costs, and AI helping develop its own infrastructure, will shape how widely those capabilities spread.
My experience with ChatGPT, Codex, and Claude, and why exploring unclear needs, staying focused, and correcting course matter more to me than execution alone.
My account was suspended during identity verification after upgrading to Claude Max. The experience raised a larger question about accountability as AI becomes more important to our ability to work.
试用 Claude Fable 5 后，我认为 AI 的能力已经跨过一道门槛。接下来，成本下降以及 AI 对基础设施研发的参与，将决定这种能力如何普及。
从 ChatGPT、Codex 和 Claude 的使用体验出发，谈我为什么更看重 AI 探索模糊需求、保持目标和自我纠错的能力。
升级 Claude Max 后，在身份验证过程中收到停权通知。这次经历让我思考：当 AI 越来越影响工作能力时，提供它的公司应该受到怎样的约束。
