You like it or not, vibe coding is now part of development. And metrics will eventually be used to understand how well each developer works with LLMs.

It’s not that different from algorithms:

There’s O(1) - cost barely grows And there’s O(n²) - double the input, and suddenly everything explodes

Now take two developers.

One constrains the LLM upfront. Set boundaries. Clear intent. Thinks ahead about where the model might stumble. Fewer prompts, fewer fixes, predictable token cost.

The other writes a vague prompt, clicks “accept all changes”, and spends the rest of the day asking the questions like: why doesn’t this button work and what the hell just happened?

Only one scales once you measure implementation speed against tokens consumed.

➡️ Speed alone hides inefficiency. ➡️ Speed plus token usage exposes it.

Vibe coding makes individuals faster. Token-efficient vibe coding scales teams.
