Kimi K3 nears the top of AA-Briefcase, but its presentation score trails
ArtificialAnlys · x · 2026-07-22
Artificial Analysis says AA-Briefcase evaluates models on three axes: binary correctness, analytical quality, and presentation quality. Kimi K3 lands near the top overall, but its presentation score lags behind its analytical score.
- Analytical Quality Elo: 1754, roughly in Claude Fable 5 territory (1744).
- Presentation Elo: 1471, below some models it outranks overall, including GPT-5.6 Sol (max) and Claude Opus 4.8 (max).
- The benchmark’s combined Elo blends correctness, analytical quality, and presentation quality into one score.
- A follow-up note says Kimi K3 is second only to Fable 5 on AA-Briefcase, but it costs more than Opus 4.8 to run and averages nearly an hour per task.
