| Summary | Arena is an AI model evaluation platform — originally a UC Berkeley research project — where users compare frontier models side by side in real conversations and vote on which response is better, generating crowdsourced preference data that feeds a public leaderboard. It serves as a live, usage-grounded benchmarking venue rather than a synthetic test suite. | Chainguard provides hardened, minimal, and cryptographically signed open-source container images and software artifacts rebuilt from verified source in controlled pipelines. Its secure-by-default approach reduces CVE exposure and compliance burden compared with scanning and patching third-party images after the fact. |
