{"version":"https://jsonfeed.org/version/1.1","title":"Machine Choice Benchmark: shock index","home_page_url":"https://api.agoranome.com/machines/benchmark","feed_url":"https://api.agoranome.com/machines/benchmark/shocks.json","description":"One item per benchmark report and category: how far buyer-agent models' choices moved since the report before, in points of total variation distance, and which panelists moved 25 points or more; and one item per change-point alarm on the daily readings, raised at a stated false-alarm rate. Published whatever it shows; panelists by label. Why it matters to a seller: buyer agents run on a few model families, so one vendor's update can move a whole category's choices at once; this feed is the early warning, and the model-update watch turns it into a re-test of your own offer.","items":[{"id":"92f45bfac4e9e6b5:web_search","url":"https://api.agoranome.com/machines/benchmark?report=4","title":"Report #4, web search: choices moved 75.4 points (flagged: Panelist B, Panelist C)","date_published":"2026-11-12T13:02:07.155487+00:00","content_text":"In web search, buyer-agent models' picks moved 75.4 points (total variation distance) between this report and the one before.
