O Gemini quebrou? Por que mudei para o Codex 5.4

If Gemini was my right-hand man in programming, lately it has let me down, and I've had to look for alternatives to avoid stalling the development of my system. In this video, I'll be honest about my real-life experience of two months using Gemini to build Promovaweb's internal LMS and how the quality of the 3.1 Pro model has drastically degraded in recent weeks.

In contrast, I tested Codex 5.4 and the result was brutal: much cleaner, optimized code and an assertiveness that makes me twice as productive, even with the message limitations. I'll show you why, for complex systems, Gemini is losing steam while Codex delivers senior programmer performance. I'll also talk about our AI Makers and Founders training programs, for those who don't want to go through this journey alone and want to accelerate the launch of their product or SaaS with the support of our community. If you feel your AI productivity has dropped or want to know which model to choose for your back-end, this discussion is essential. 00:00:00 Degradation and latency in Gemini 3.1 00:01:02 Serious errors: Test breakage and database deletion 00:01:38 Differences in usage between Gemini 3.1 Pro and 3.0 Flash 00:02:40 Problems with MCP and Skills in Laravel 00:04:51 Failures in migration creation and architecture 00:07:22 Gemini for programmers vs. VibeCoders 00:10:04 The turning point with Codex 5.4 00:11:40 Code quality comparison: Gemini vs. Codex 00:14:18 Productivity and message limits 00:17:30 Resource consumption and CLI performance 00:18:02 Gemini's strengths: Design and Landing Pages 00:19:05 AI Makers and Founders Training at Promovaweb 00:23:17 Consulting and final tool tips #Gemini #Codex #AIProgramming #Laravel #VibeCoding #SaaS #SoftwareDevelopment #Astro #AI #Promovaweb
