Evaluation results published by [Artificial Analysis](https://artificialanalysis.ai/evaluations/artificial-analysis-decision-index). undefined

Artificial Analysis publishes the Decision Index v1.0 as a live leaderboard of decision models, models that answer a typed question in one call with a probability for each option. Weighted average of AA-Omniscience-Decision accuracy and non-hallucination rate (12.5% each), HLE-MultiChoice, When2Call and WildGuardTest (25% each).

Artificial Analysis runs every evaluation itself, so these are independent measurements and not provider reports. We mirror its decision-model rows and keep the language-model baselines it runs for comparison on its own page.

Scores are rounded to one decimal; Artificial Analysis charts print integers. The index is a different protocol from Decision Index 0.2.1 and 0.3, so values do not carry across.

## About Artificial Analysis Decision Index

- Year: 2026
- Format: Weighted average, 0 to 100
- Difficulty: Weighted average of four decision-model evaluations
- Paper: [Artificial Analysis Decision Index v1.0](https://artificialanalysis.ai/articles/artificial-analysis-decision-index)

Artificial Analysis runs every evaluation itself and poses each question as one typed decision with a probability for each option. We mirror its decision-model rows, round values to one decimal, and keep the language-model baselines it also runs on its own page. These results are separate from Decision Index 0.2.1, Decision Index 0.3, JevBench, and general model rankings.

Artificial Analysis Decision Index is currently displayed on BenchLM for reference, but it is excluded from the weighted scoring formula.
