Is GPT-5 Codex actually useful for real developers? I tested it so you don't have to 🔥 Recently, OpenAI introduced GPT-5.3-Codex — a powerful AI model built specifically for real-world software engineering workflows. In this video, I try GPT-5.3-Codex for the first time and explore how it works in a practical developer setup. We’ll look at: What GPT-5.3-Codex actually is How it differs from other AI coding models Using the Codex Mac app Exploring the Codex CLI Integrating Codex with GitHub Enabling and testing AI-powered PR reviews With strong competition from tools like Claude and Gemini, the AI coding space is evolving fast. So the real question is — is GPT-5.3-Codex actually worth using in real development workflows? This video walks through my honest first impressions and a hands-on demo so you can decide for yourself. If you're a developer exploring AI-assisted engineering tools, this deep dive will help you understand where Codex fits into modern workflows. 🔔 Subscribe for more On Integration Ninjas, we break down AI tools, backend systems, and real-world engineering workflows.
