Artificial Analysis Updates Intelligence Index to v4.2 with New Evaluations and Private Test Sets
Key points
- Intelligence Index v4.2 released as an interim update.
- Introduces AA-Briefcase for agentic knowledge work evaluation.
- Adds Surge's GDP.pdf for long-context document reasoning across 4,592 pages.
- Increases weighting of private, held-out test sets to 40%.
Interim Update to Intelligence Index
Artificial Analysis has launched Intelligence Index v4.2, an interim release designed to incorporate more challenging and realistic evaluation tasks. This update precedes the upcoming v5 release and addresses the rapid pace of development in AI models, ensuring the Index remains a current and useful benchmark.
New Evaluation Components
The v4.2 update introduces two significant new evaluations. AA-Briefcase is an in-house evaluation that assesses models on agentic knowledge work tasks within complex, multi-week projects, using a private test set. Additionally, GDP.pdf, developed by Surge AI, evaluates single-turn professional document reasoning across 100 PDFs and 4,592 pages, requiring models to synthesize evidence from various formats like text, tables, and charts.
Enhanced Gaming Prevention
To prevent models from optimizing specifically for the evaluation, Intelligence Index v4.2 has increased the weighting of private, held-out test sets to 40%, doubling the previous figure. This change, along with the introduction of new private test sets, aims to provide a more accurate measure of real-world model capabilities.
Context and Future Plans
The update was expedited due to the rapid advancements in AI over recent weeks, following an eight-month period since the launch of Index v4. Artificial Analysis plans more incremental releases in the near future as development continues on the full v5 of the Index.
