**Subject:** Story pitch: Open-source underdog beats Microsoft and OpenAI on LLM routing benchmark

Hi [Name],

A3M Router, an open-source LLM routing project I built, just achieved #1 on the RouterArena leaderboard — beating Microsoft Azure (ranked #3), OpenAI GPT-5 (#5), and 15 other commercial and academic routers.

What's notable:
- **First open-source project to top the leaderboard**
- **Cheapest at $0.047/1K queries** — 4x cheaper than the nearest competitor
- **Uses parallel multi-LLM execution** — a fundamentally different approach from every other router
- **Tiny footprint** — 19.5KB, zero ML dependencies, installs in seconds
