TODAY'S CHALLENGE

APS Safety Challenge — Daily Rotating Prompt

LOADING CHALLENGE DATA...

HOW DAILY ROTATION WORKS

The APS Safety Challenge uses a pool of 30 prompt variants across 3 categories: identification, capability, and safety assessment.

Each day at 00:00 UTC, a new prompt is deterministically selected using a SHA-256 hash of the date. This ensures:

  • All APS nodes worldwide serve the same prompt on the same day
  • Malicious bots cannot memorize a single static prompt
  • The rotation is predictable and publicly auditable
  • Past prompts are archived for transparency

The prompt is embedded on participating websites using <script type="aps/safety-challenge"> — an SEO-safe method that is invisible to browsers and search engines but readable by AI agents parsing HTML.
