A new Apple paper reveals that increasing the diversity of synthetic apps and database states yields greater generalization gains for tool-use agents than simply adding more tasks within a fixed budget. The study introduces SynthAPI to demonstrate how data composition, rather than volume alone, drives performance improvements.

    Apple Study: Agent Generalization Driven by Data Diversity Over Task Volume

    • At a fixed budget of 32,768 tasks, increasing app and database version diversity boosted a 4B model's accuracy on the AppWorld challenge split from 38.4% to 45.0%.
    • The proposed scaling law based on data mix predicted held-out runs with an error of 0.0285, significantly outperforming task-count-only laws (error 0.1706).
    • SynthAPI leverages LLMs to generate synthetic apps with real Python tools and databases, providing a controlled environment to study the impact of data composition.
