Briefings

AlphaDiana is a new measurement system for AI agents that links execution conditions to outcomes, behavior, and resource use. It supports modular interfaces for datasets, agents, environments, and scorers while preserving harness-native control loops. The study tested three open-source models and three open-source harnesses on five answer-based benchmarks, finding that harnesses do not consistently improve accuracy. Key findings include that gains on unsolved questions can be outweighed by losses on correctly answered ones, and that both skill guidance and retained history fail to reliably improve accuracy.

Key points

• AlphaDiana introduces a modular measurement system for AI agents that links execution conditions to outcomes, behavior, and resource use.
• The study tested three open-source models and three open-source harnesses on five answer-based benchmarks, finding that harnesses do not consistently improve accuracy.

Context

This research addresses the need to understand agent performance by linking execution conditions to outcomes, behavior, and resource use. It provides a framework for comparing agents and diagnosing failures under shared task and resource policies.

Limitations

The evidence covers only three open-source models and three open-source harnesses on five answer-based benchmarks, with two additional models tested on interactive benchmarks. The study does not provide causal claims or opinions, and findings are based on observed behaviors rather than forecasts.
