Which AI indexes does SIREN contrast?

Search often lands on a doom score, a countdown, or a DEFCON-shaped novelty page. These versus pages state what each rival measures and what SIREN refuses to claim. No borrowed doom probability, AGI date, or military DEFCON reading.

5Rival pages
  1. SIREN vs DoomBench: which should you use? Live AI Doom Index. SIREN does not score takeover risk. It counts how loud AI activity is this hour, from public feeds, with a receipt.
  2. SIREN vs Skynet Countdown: which should you use? AI risk predictor & AGI timeline tracker. SIREN publishes no AGI date and no control-loss percentage. It publishes an hourly activity score you can recompute.
  3. SIREN vs p(doom) clocks: which should you use? Probability-of-doom countdowns. SIREN does not publish a p(doom). It counts observable tempo. For the vocabulary, see the p(doom) explainer.
  4. SIREN vs PizzINT: which should you use? Pentagon Pizza Index with DEFCON / Doomsday Clock framing. SIREN does not publish a DEFCON level or a Doomsday Clock reading. It publishes an hourly AI activity score you can recompute from public data.
  5. SIREN vs Takeoff Tracker: which should you use? AGI metrics dashboard (timelines, stocks, leaderboards, p(doom) estimates). SIREN does not publish an AGI timeline, a takeoff dashboard, or anyone’s p(doom). It publishes one hourly recomputable activity score from public feeds.

What questions do people actually ask?

Where are the SIREN versus pages?

Each rival has a dedicated /vs/ page: DoomBench, Skynet Countdown, p(doom) clocks, PizzINT and Takeoff Tracker. This hub lists them. The full table is on /compare.html.

Does SIREN claim to beat DoomBench or Skynet on doom risk?

No. Those sites score judgement about danger or timelines. SIREN counts how loud AI activity is this hour. The versus pages only contrast measurement methods.
