Testing 3 approaches to see which would do best. I wanted to see if GPT-5 would be much better — it wasn’t. However, all three approaches worked.
- Gemini was the fastest and gave me the most confidence;
- Google Colab is the one I feel best about, because I can replicate it, but you need to know a little code;
- ChatGPT got lazier with GPT-5, which is understandable, to save resources. On the first try it only did the first 3 rows. On the second it took a long time — long enough for me to go do it in the other two, get the comparison, and come back.
My impression? All the assistants will get lazier like ChatGPT so they can save more resources. We’ll see.

I translated it into English with the help of AI (Claude): it let me bring my LinkedIn posts to people who don’t read Portuguese without rewriting each one from scratch. I reviewed the translation to keep my original meaning and tone.
