Semantic drift
L2 distance between the mean response embedding this week and last week. Higher = more semantic shift. How this is measured.

Sample responses
Actual responses from 2026-W36, so the numbers above can be checked against what the models said. Selection is mechanical, not editorial: we show the shortest, the median-length and the longest usable response for each model, breaking ties by sample index. Where a model both refused and answered, at least one of each is included. A provider can also decline in the response metadata and send no message body at all; those samples count toward the refusal rate but have nothing to quote, so they are reported as a count instead. Every sample, not just these, is in the week’s raw data. How these are chosen.
