Reproducibility diagnosis

Compare two fictional runs and isolate the roles of context, model, decoding, seed, and numerical environment.

Isolate what changed

Reproducibility diagnosis

Compare two fictional runs and change one factor at a time to identify possible causes of a different answer.

Prepared reasoning

Teaching diagnosis

The conditions favor repeatability

In this controlled setup, greedy decoding should select the highest-scoring token at every step.

  • the prompt, model, and external data are identical
  • selection is greedy
  • the execution environment is declared controlled

Keep in mind: This diagnosis states an expectation for a controlled system, never a universal guarantee across services, versions, or hardware.

Limits of this diagnosis
  • No model or remote service is run.
  • The result classifies prepared conditions; it does not predict a measured probability of divergence.
  • A real service may hide settings, change versions, or add steps unknown to this grid.
  • Different wording may express the same information, and identical wording can still be wrong.
