Start with the mechanism
Three steps to keep in mind
- 1
Compare the inputs
Hidden instructions, history, retrieved documents, and formatting all belong to the context.
- 2
Compare decoding
Temperature, top-k, top-p, penalties, and the seed can change token selection.
- 3
Compare the system
Model versions, libraries, hardware, and parallel execution may affect reproducibility.
Try it yourself
The lab isolates this mechanism with a small, transparent simulation. Everything runs locally in your browser.

Technical detailWhat the short version leaves out
Greedy decoding removes the random draw at each local step, but it does not guarantee identical results across every infrastructure.
To diagnose variation, change one factor at a time and record the complete configuration.
