Engineering & product insights
Deep dives on AI routing, semantic search, production ML, and how we build StrataRouter.
Inside StrataRouter's Semantic Cache: 85%+ Hit Rates in Production
Most semantic caches fail in production because they use exact hash matching. We use blake3 hashes combined with configurable semantic similarity thresholds. Here's the full design and the production numbers.
HNSW Indexing for Real-Time Semantic Routing: A Production Guide
Hierarchical Navigable Small World graphs give us O(log n) approximate nearest-neighbor search. We explain the algorithm from scratch, walk through our SIMD-accelerated implementation, and share the tuning parameters that matter most.
Building SOC 2-Ready AI Infrastructure with StrataRouter Enterprise
Enterprise AI teams face a growing compliance burden. We designed StrataRouter's audit trail module from the ground up for SOC 2, HIPAA, and ISO 27001. This post walks through the cryptographic design and what auditors actually check for.
