Why it’s minor
Which products a model recommends is read out of its answer by the least reliable part of our scorer, so compare the two answers before reading much into this.
The full answers
Each answer as the API returned it, with its Markdown rendered for reading. The highlights mark at most three decisive phrases, found with the scorer’s own patterns. Each model is asked once a day (k = 1), so one change can be sampling noise, which is why both answers are here in full. How scoring works.
