This explanation of AI as “next-word prediction” is accurate — and the article does a strong job breaking down attention, tokens, and how the system actually works.
But there’s one layer missing.
Everything described here happens inside a single pass:
tokens → attention → probabilities → next word.
In real use, though, that process doesn’t happen once.
It happens across turns — with interaction.
So a more complete way to say it is:
“It predicts the next word under continuously updated constraints imposed by interaction.”
Because the user isn’t just providing input.
They are:
• reinforcing or rejecting outputs
• shifting tone and framing
• applying pressure for precision
• and shaping what the model prioritizes next
The model computes probabilities.
The interaction reshapes them over time.
That layer isn’t in most explanations — but it’s where the system actually becomes useful.
Thank you — glad the cocktail party framing landed!
You're touching on something important. The "Are Sixteen Heads Really Better than One?" paper showed exactly this: many attention heads become redundant in deeper layers, and you can often prune 40-60% of them with minimal performance loss.
It's a fascinating tension — we design for diversity, but the model learns toward convergence. Great fodder for a future post on efficient transformers and why smaller models can punch above their weight.

Totally agree. This is an intro. I am going in much more detail in many of my other articles.
