I’ve found myself being much “nicer” to gpt 5.5, going out of my way to compliment the work in ways I never did before. It feels like working with a higher intelligence. I was never rude to other models, but caught myself being more aggressive in the past.

So it can basically understand how to build apps and tools for anything you throw at it. For example, I recently bought this device, a small e-reader. It fully understood the firmware, and now I am making apps for it! Or even making full apps/games for my Flipper Zero.

GPT-5.5 Unlocks Vibe Hardware Era for AI Workflows
By

GPT-5.5 is the highest leverage tool I have ever touched.
— Pietro Schirano (@skirano) 23 avril 2026
For the first time, I don’t feel limited by what a model can do. I feel limited only by what I can imagine.
Training workflows. Impossible optimizations. Hardware experiments over USB.
