reaatech/otel-cost-exporter
These packages convert GenAI semantic convention spans into real-time USD cost metrics, exporting them via Prometheus, OTLP, or JSON. You would adopt them to track LLM spend per model and provider without manually maintaining pricing tables for OpenAI, Anthropic, Google, AWS Bedrock, and Azure. The packages compose as a layered pipeline—core types, pricing tables, a calculator with LRU caching, and an exporter that can run either as an in-process Node.js SpanProcessor or as a standalone OTLP collector.

@reaatech/otel-cost-exporter

@reaatech/otel-cost-exporter-calculator
A cost calculator that converts raw token counts from GenAI semantic convention spans into per-model cost breakdowns in USD, with model name normalization, provider detection, and LRU pricing caching. It provides a `CostCalculator` class (or `createCostCalculator` factory) that accepts a pricing provider, cache, normalizer, and optional default price, and returns a `CostResult` with input, output, and total costs.
