Artificial Analysis revamps eval methodology, reshuffling all model scores
pranjalssh · x · 2026-09-06
- Artificial Analysis redid its eval scoring methodology, which changed scores for all models at once; critics claim it was tweaked to favor GPT6.
- The controversy highlights a recurring problem: leaderboard scores lose comparability whenever methodology shifts.
- A previously shared index design measures frontier progress without affecting historical scores when evals are added or removed; under that index GPT6 is still a clear winner. The poster endorses stable scoring, saying evals shouldn't shift every time.
