Reproducibility at Kronos
Kronos's answer to 'how do we know?' is not a claim — it is a download. The engines, inputs and expected outputs are public, and they reproduce.
The Kronos design record is deposited openly on Zenodo under CC BY 4.0. Each deposit contains the reduced-order engines, the input decks, and the expected outputs, so an independent reviewer can reproduce the published numbers rather than take them on trust.
Two tiers of reproduction
- Tier 1 — byte-exact. Deterministic calculations reproduce to the exact byte on a matching environment.
- Tier 2 — tolerance. Calculations with legitimate numerical variation reproduce within a stated tolerance.

What reproducibility does and does not proveReproducing a computation proves the result follows from the stated model and inputs. It does not prove the model matches a machine not yet operating (the HYPERION breeder is scheduled to begin construction in Q2 2027) — which is why Kronos labels its figures computed design targets.
