Over the past year, I’ve used large language models almost daily — for coding, analysis, writing, and problem-solving.
Like many developers, I was impressed by how fast they improved.
The answers got better.
The context got longer.
The reasoning felt sharper.
But the more I tried to integrate AI into real work, the more one issue kept resurfacing.
Not intelligence.
Unpredictability.
When “Ask Again” Becomes a Smell
In casual usage, we’ve normalized a strange workflow:
Ask the model a question
Ask again if the answer feels off
Compare multiple outputs
Pick the one that “looks right”
This is fine for exploration.
It’s terrible for systems.
In software engineering, repeating the same input and getting different behavior is usually a bug — not a feature.
Yet with AI, we often accept this as normal.
Why This Breaks in Real Systems
As soon as AI outputs feed into anything serious — code generation, decision support, automation — unpredictability becomes a liability.
You can’t easily:
Reproduce bugs
Audit decisions
Assign responsibility
And once you add retries, fallbacks, and manual review, complexity explodes.
At that point, the system isn’t smarter — it’s just harder to reason about.
The Real Difference Isn’t the Model
I’ve seen two very different patterns emerge:
Some developers treat AI as a brainstorming tool.
Others start treating it as a system component — with boundaries.
Same models.
Very different results.
The second group isn’t trying to squeeze more creativity out of the model.
They’re trying to limit where uncertainty is allowed to exist.
That shift alone changes everything.
Controllability Is an Engineering Problem
This isn’t about distrust or pessimism.
It’s about acknowledging a simple fact:
Probabilistic systems don’t become reliable just because they get smarter.
No amount of scaling automatically turns variability into predictability.
If we want AI to move beyond demos, we need to design around uncertainty — not pretend it will disappear.
What This Changed for Me
Personally, this realization changed how I work with AI.
Instead of asking:
“How can I get a better answer?”
I started asking:
“Where should I not rely on the model?”
That single question made my workflows simpler, safer, and easier to reuse.
Final Thought
AI doesn’t need to sound more intelligent.
It needs to behave more consistently — within clearly defined limits.
Until controllability becomes a first-class concern, AI will remain powerful but fragile in real-world systems.
