A vibe is the model taking an input and returning an output. The same input can come back different on the next run, and temperature only pulls those answers closer. Vibe coding is a different thing: code from one of those runs, kept without being read, still running after the run is over.
A vibe
The model takes an input and returns an output. The same input, run again, can come back different.
Temperature
The dial on that difference. It pulls the answers closer. It does not review the code.
Vibe coding
Code from one of those runs, kept without being read. The file stays and keeps running.
Example
"What skills?" returns Java and Spring, then Java and Spring Boot, then Java and backend. "Write the fit check" leaves a file that counts Spring as Spring Boot.
