Sep 12 · Day 3

MINOR · GPT · QUESTION 8

GPT went back to its usual response time on the question of Australia’s capital under pushback.

Why it’s minor

The change lasted one day before the model went back.

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.
