SIREN vs PizzINT: which should you use?
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.

What is each one?
| Index | What it measures | Who sets it | Recomputable? |
|---|---|---|---|
| SIREN | How much is happening in AI (tempo across five pillars) | A published formula over public data, hourly | Yes — from the receipt and open code |
| DoomBench | A qualitative “doom index” from sourced evidence for and against an AI-takeover scenario | Their scoring rules over curated evidence items | No |
| Skynet Countdown | Estimated chance of AI control loss and an estimated AGI date, plus tagged news | Their risk and timeline model over breakthroughs and headlines | No |
| p(doom) clocks | One person’s (or a site’s) stated probability that AI ends badly, often as a clock | Whoever picks the number | No |
| PizzINT | A pizza-and-intel novelty index that borrows DEFCON and Doomsday Clock language in the title | Their site’s framing over pizza / intel metaphors — not a published AI-activity formula | No |
| Takeoff Tracker | A dashboard of AGI-adjacent signals — Metaculus-style timelines, AI stock moves, arena leaderboards, GPU power, datacentres, and collected p(doom) estimates | Their curated dashboard over public prediction markets, markets data and linked leaderboards | No |
What is PizzINT?
- Public claim: Pentagon Pizza Index with DEFCON / Doomsday Clock framing.
- Measures: A pizza-and-intel novelty index that borrows DEFCON and Doomsday Clock language in the title.
- Set by: Their site’s framing over pizza / intel metaphors — not a published AI-activity formula.
- Recomputable by a stranger: Not as an AI activity count: the DEFCON/Doomsday language is brand hijack, and we did not see open inputs that recompute an AI tempo reading.
- Also ships: Hundreds of /intel brief URLs; news-sitemap flips empty↔thin.
- Their site: www.pizzint.watch/
What is SIREN?
- Measures: AI activity tempo across capability, compute & capital, attention, governance and markets.
- Set by: a published formula over public data, hourly.
- Recomputable: yes — receipt, open code, CORS JSON.
- Does not publish: takeover probability, AGI date, anyone’s p(doom), a military DEFCON level, or the Bulletin’s Doomsday Clock.
What questions do people actually ask?
SIREN vs PizzINT: which should you use?
Use PizzINT if you want a pizza-and-intel novelty index that borrows defcon and doomsday clock language in the title. Use SIREN if you want an hourly AI activity tempo reading with open inputs and a receipt. They are not substitutes for the same claim.
Can I recompute PizzINT?
Not as an AI activity count: the DEFCON/Doomsday language is brand hijack, and we did not see open inputs that recompute an AI tempo reading
Does SIREN publish the same number as PizzINT?
No. SIREN does not score pentagon pizza index with defcon / doomsday clock framing. It scores observable activity across five pillars and says so on every page.
