$ how the score was worked out · GenAI-Arena (TIGER-Lab) text-… 96%
Each result implies a score on its own, after adjusting for how hard its test is and who ran it. The score is their weighted average, with a small pull toward the middle for thinly tested models. Each test's weight is its counts column above; here it's added up by who ran the tests. How it works
| source | results | share of the score |
|---|---|---|
| 1 | 96% | |
| prior · pull toward the middle | 4% | |
| weighted average | = 31.8 |
