ついつい悪い癖が出て,「各社生成AIに同じプロンプトを打ち込んだら,それぞれどんなコードを出してくるか」試してみたくなってしまいました。
そこでGemini, ChatGPT, Claudeのそれぞれに以下のプロンプトを入力してコードを出させてみました。
人工脳脊髄液を1M濃度の各種ストック溶液から希釈調製するためのWebアプリを作製してください。
ほんとになにも微調整なしのプロンプト一発の比較です。各社それぞれに特徴が出ていて面白いですね。

Testing an LMM-Based Web App
I tried building a small web app using Gemini, ChatGPT, and Claude.
With just a simple prompt, it was able to generate a working prototype surprisingly quickly. The overall structure and basic functionality were mostly usable right out of the box.
Of course, the output wasn’t perfect—there were some rough edges in both the interface and the logic. But with a bit of manual tweaking, it became sufficiently practical for everyday use.
What stood out was how easy it is to go from idea to something tangible. Even without writing everything from scratch, you can quickly assemble tools that are “good enough” for personal workflows.
I’ve uploaded the resulting app as an HTML file.
Feel free to try it out or modify it as needed.
