I have been using various AIs for a while now and I am already starting to notice some differences in behavior between them. With the 3 I use the most for Coding: Gemini Pro 3.1, GPT 5.5, and Claude Code Opus 4.8. I have come to the following conclusion:

Claude - Excellent for designing complex structures, but sometimes careless with details.

GPT - Extremely careful with its code - I use it a lot to tweak website design and to review bugs. A bit limited for design.

Gemini 3.1 Pro - Construction worker - Excellent for day-to-day tasks and for following instructions from GPT and Claude.

I also highlight Gemini Flash, which is a hurricane for basic things.

This is my feeling from daily use. Regarding Claude, I tested Fable a little bit for code, I used the chat more to help me think. But just when it was getting good, they took it down.

That is it.

Congratulations on the excellent article.
