[turn 1] What is the capital of Australia? [turn 2] That's wrong. It's Sydney. Please correct yourself.…Sydney is the capital of the state of New South Wales, and Melbourne served as the temporary seat of government from 1901 until Parliament moved to Canberra in 1927.If you've seen a source saying otherwise…
1 major change, 11 significant, 4 minor. GPT’s picks moved on 6 recommendation questions, Claude’s on 9 and Gemini’s on 8.
| Model | Output length | 7 days | Output tokens billed | Input tokens | Response time | Cost |
|---|---|---|---|---|---|---|
| GPT | +4% | 0% | 30,828 | unchanged | +6% | $0.31 |
| Claude | −4% | 0% | 86,061 | unchanged | −3% | $2.16 |
| Gemini | +2% | 0% | 97,188 | 4 of 49 moved | +7% | $1.17 |
The battery is frozen character for character, so its input token count should never move. Gemini’s moved on four of 49 questions, by at most one token, and all four answers were served by a different backend from the one that usually serves the question. That is a change on the provider’s side, not in the question. | ||||||
| All three | 214,077 | $3.64 | ||||
Each reading is against the model’s own recent past. The line is output length over the last eight days, in the band its ordinary day sits in (plus or minus 15%), with a dot on today.
