# Determinism

Everyone benchmarks accuracy; nobody benchmarks whether a model gives the same answer twice.

For production video systems — safety, compliance, robotics — a 92%-accurate nondeterministic
model is unshippable, while a deterministic model with known failure modes is an engineering
component. Darwin's perception runs in embedding space with calibrated confidence scores;
language enters only at the query layer, never the perception layer — so outputs are repeatable.
