# Jev Logs

> Open-source TypeScript log triage. Score, prioritize, and route OpenTelemetry logs with TypeSafe’s Jev before expensive LLM analysis. MIT licensed. npm package `jevlogs` v0.3.0. Requires Node.js 22+.

Jev Logs is a small decision layer between your logs and your LLM bill. It keeps every record. Only confidently low-value, low-priority events may skip a separate analysis branch. Errors, protected records, timeouts, and uncertain answers stay eligible for analysis.

This is a public preview. Production accuracy and savings have not been independently validated. Independent project — not affiliated with TypeSafe, Vercel, GitHub, or OpenTelemetry. The hosted model is TypeSafe’s Jev via Vercel AI Gateway; this repository is the integration SDK.

Do not send API keys or production logs to the website. Live evaluation uses `AI_GATEWAY_API_KEY` on your machine.
