Benchmarks

Controlled comparisons computed live from our deterministic engine modules. Every cell is recomputed at build and verified, so a benchmark figure can never drift from the engine that produced it. Each table downloads as CSV and is free to cite. These compare engine outputs, not vendor marketing claims.
