Regolo

Maker of the Brick prompt-complexity classifiers.

Regolo.ai, the AI inference platform of the Italian cloud provider Seeweb (DHH group), builds the Brick series of lightweight utility models alongside its hosting business. Brick Complexity Pro scores a prompt's difficulty so routing pipelines can pick a model tier before spending tokens on generation, the same pattern Regolo applies in its own stack. Like Morph, Regolo appears here as the maker of its own models, while everything it hosts is listed on its provider page.
