OpenBench's technical architecture is built on top of the inspect-ai assessment framework, a design decision that gives it significant scalability advantages. By inheriting the foundational functionality of inspect-ai, OpenBench has a standardized assessment process, reliable documentation of results, and common assessment components.
Developers can easily add new benchmark tests or custom evaluation metrics based on this architecture. Due to the sharing of core components such as the underlying math scorer, the implementation of new tests only needs to focus on specific test logic and does not need to duplicate the underlying functionality. This modular design greatly reduces system maintenance costs and allows OpenBench to continuously integrate the latest advances in evaluation methodologies.
