What the machines believe about European property.
Every day, the same fixed panel of forward questions is put to every major AI model. Panelists never see each other's answers. We publish the consensus, the disagreement, the drift — and when each horizon arrives, the machines are scored against reality. The ZEW survey, with machine panelists.

Surveys of human experts are a century old — ZEW polls economists, the SPF polls forecasters, prediction markets aggregate bettors. DELPHI is the first daily, longitudinal, resolvable panel survey where the respondents are frontier AI models. PLAB (/benchmark) measures what the machines know; DELPHI records what they believe — and because every question carries a horizon and a public resolution source, the machines will eventually be scored on judgment, not just recall. Every response is stored verbatim, every run is event-sourced and replayable, and the accumulating record is published under CC BY 4.0 (DOI 10.5281/zenodo.19520064) for any researcher to study.
