Safety & Crisis Detection

A tiered detection cascade with per-tier latency readouts.

Production proof: Demo version of my production cascade: >99% of traffic resolved in <100 ms at ~99.7% accuracy. Read the case study →

How it’s engineered
  • Tier 1 is a compiled pattern screen that resolves the obvious cases in well under a millisecond, exactly how you keep p99 latency flat.
  • Tier 2 embeds the message in-browser (MiniLM) and compares it against risk prototypes by cosine similarity, catching phrasing that patterns miss.
  • In production a third LLM tier reviews only the ambiguous residue, so >99% of traffic never pays LLM latency or cost.
  • The point of a cascade: accuracy where it matters, milliseconds and near-zero cost everywhere else.
