-Cortex delivers a **5.2x geometric mean speedup** — see [Brainy vs Cortex](/docs/cortex/comparison) for measured benchmarks.
+Cortex registers native (Rust/SIMD) vector, metadata, and graph engines behind the same Brainy `find()` API — no code changes, an optional dependency for production-scale workloads.
