A
Arena is a community platform where millions of users benchmark frontier AI models against real-world tasks and vote on outputs—creating a public leaderboard grounded in production feedback rather than synthetic benchmarks. The stack is heavy on data infrastructure (Spark, Airflow, PostgreSQL, low-latency event streams) and security tooling (CrowdStrike, Cloudflare One, threat modeling), reflecting two acute scaling pressures: maintaining leaderboard integrity under adversarial conditions and building pipelines that ingest millions of evaluation signals at scale.
