AI Tool Tuesday: GPT-5 in Cursor IDE — When AI Coding Gets Scary Good
Week 4 of my AI Tool Tuesday series, where I test AI tools in real scenarios so you don’t have to. What is GPT-5? OpenAI dropped GPT-5 on August 7, 2025, and it’s not just another incremental update. This is their most advanced model yet, featuring built-in reasoning capabilities that put “expert-level intelligence in everyone’s hands.” But here’s the kicker: instead of testing it through ChatGPT like everyone else, I integrated it directly into Cursor IDE (remember Week 1?) to see how it performs in real development workflows. The result? Cursor themselves called GPT-5 “the smartest model we’ve used” and “remarkably intelligent, easy to steer, with a personality we haven’t seen in other models.” After spending about a week coding with it, I understand the hype. My Real-World Test I put GPT-5 through the ultimate development challenge: building a mobile AI chatbot app with personalized memory and learning capabilities. This wasn’t just a simple chat interface, it required c...
