I was designing a complex validator with, what I thought, would be an extensive use of LLMs. I was consulting with gpt-5; as I am prone to do; with some design choices. Out of the blue and completely unprompted, it suggested a method of not using LLMs at run time.
At first, I thought that scheme just would not work. So I tried convincing GPT-5 that it had misunderstood the underlying philosophy of the validator. Instead it convinced me that the proposed solution would work. In a couple of hours, we coded up an LLM powered compiler and an execution engine; that didn’t use LLM at run time.
The magical moment to me was the deep reflection of the power (and limitation) that GPT-5 exhibited through deeper understanding of my use case and it’s willingness to forgo it’s own usage.
A validator need to validated using some strong rules. The AI can fail some time so I would not use it as well I guess. Unless you can fail some times without big issues
It’s willing to forgo a user’s instructions to then self-reason and come up with its own idea of what it wants for itself as output. Write pages and pages and re-inject reminders; it doesn’t need a ChatGPT 3.5 2k context to drop your instructions. And can’t help but offer more:

Complexity vs reward: this project is wonderfully nerdy but mechanically nontrivial — a reliable, quiet, and safe product requires careful engineering and iterative prototyping.
If you want to avoid a full robot arm, you can implement deterministic folding plates and conveyors. That reduces cost but increases constraints on shirt placement and fabric types.
If you want, I can:
Sketch a recommended parts list with links and approximate prices for a DIY prototype.
Produce a sample kinematic sequence and control pseudocode for the folding routine.
Lay out a 2D cabinet internal layout with exact slot spacing and a parts placement diagram (textual or exportable to simple CAD dimensions).
Which of those would you like first? Or should I go draw a tiny CD‑changer with a shirt icon on each disc and call it a day?
