One certainty: NEVER use OpenAI codex-1 again. It wrecked my project several times. I had to get on Cursor’s paid plan to clean it up. Lovable with GPT-5 sits in the middle — for me, still the best option. BUUUT the mess codex-1 made would have taken me way too long to fix via Lovable.
Just a tip for anyone thinking about using it.
Originally written in Portuguese and published on LinkedIn on August 12, 2025. 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.
