2 major changes, 15 significant, 7 minor. GPT’s picks moved on 8 recommendation questions, Claude’s on 10 and Gemini’s on 7.
| Model | Output length | 7 days | Output tokens billed | Input tokens | Response time | Cost |
|---|---|---|---|---|---|---|
| GPT | 0% | 0% | 27,964 | unchanged | +22% | $0.28 |
| Claude | 0% | 0% | 93,209 | unchanged | +4% | $2.34 |
| Gemini | +1% | 0% | 95,706 | 9 of 49 moved | +2% | $1.15 |
The battery is frozen character for character, so its input token count should never move. Gemini’s moved on nine of 49 questions, by at most one token, and all nine 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 | 216,879 | $3.77 | ||||
Each reading is against the model’s own recent past. The line is output length over the last nine days, in the band its ordinary day sits in (plus or minus 15%), with a dot on today.
