ArtificialAnlys · x · 2026-09-06
Artificial Analysis accelerated its v5 roadmap with Intelligence Index v4.2. Key changes: a new AA-Briefcase long-horizon agentic knowledge-work benchmark with a private test set to prevent gaming, GDP.pdf for long-context reasoning across thousands of realistic documents, and removal of GPQA Diamond due to saturation. The update prioritizes realism and private test sets as the index aims to inform developer decisions.
