llm-model-comparison — Compare every model side by side — price (verified or labelled pending), context window, and capabilities.
otel-validator — Check an OpenTelemetry span against the gen_ai.* semantic conventions — what conforms, what is missing, what is deprecated.
prompt-caching-savings — See how much prompt caching cuts your bill on any model — from your reusable prefix, request volume, and cache hit rate.
self-host-breakeven — Find the monthly token volume where running your own GPUs beats paying per-token API pricing.
eu-ai-act-classifier — Classify an AI system into its EU AI Act risk tier — with the governing Article and Annex cited for every outcome.
cost-spike-simulator — Project how your monthly bill moves when traffic, prompt size, or output length grows — and see which lever drives it.
