AI safety evaluation lab cover with shield and gauge motif

AI safety evaluation lab

A hands-on harness for black-box LLM safety evaluations: a scenario runs against a target model, the response flows through an evaluator DAG combining LLM-as-judge with semantic analysis, and scores are aggregated into a report streamed live to the browser over SSE.

It also includes a "semantic space lab" for exploring embedding geometry against a locally hosted model — cosine similarity, 2D PCA projections, and vector arithmetic (A − B + C) — useful for building intuition about what embedders actually encode.
