其他模型 GLM 4.6 、M2、KAT-Coder 都未完成作业。能进入编码阶段的是 GLM 4.6，但是代码里边一堆 document 导致 Next.js 报错太多就没往下走了。M2、KAT-Coder 在技术方案阶段没满意的产出，有的是工具不调用、有的是不听话。

这周一直在实践 SpecKit （宪章 -> 需求澄清 -> 技术方案 -> 编码 -> 检查改进） 规范 AI 编程，尝试不写代码来构建一个复杂一点的应用。
题目是：使用“mediabunny”构建一个音视频格式转换的网页应用，不使用服务端和 FFMPEG.wasm。
选用“mediabunny”的原因是：新出现的 npm 库大模型的知识库里边没具体知识，模型必须使用工具才能完成。
最终能交作业的模型是 Codex 和 Sonnet 4.5。Codex 的 UI 挺好的，Sonnet 4.5 做出来了，但是 UI 太 AI 了。

Hard agree, I'm making more use of spec frameworks too (speckit) and it's hard to deny the productivity boost.
It does create a different relationship with your codebase though that I'm trying to get used to.

Had a come to Jesus with #Claude and #SpecKit tonight.
Me: "Would analyzing my actual repo help evaluate if SpecKit is genuinely useful or just a security blanket?"
Claude: "Yes, let me look at the evidence."

SpecKit 使ってみてるけど、ちょっと扱いが難しいなぁ、spec ごとにブランチが状態を持っちゃってる?から、取り回しが悪いと思ってしまった。
SDD 自体は SpecKit じゃなくてもできるし、使わなければいいだけの話ではあるけど、単に使いこなせていない可能性もあるから、もう少しウォッチしておこう。

Okay so SpecKit just seems to be a whole thing where they convince you to use up as many tokens and premium requests as possible writing 15 markdown files to change 20 lines of code and that's just fucking hilarious to me.
