Brick Complexity Pro

by Regolo

Regolo.ai built Brick Complexity Pro as the hosted endpoint of the complexity stage in Brick, its open-source semantic router. Instead of generating answers, the model reads an incoming prompt and returns a difficulty grade of easy, medium, or hard, judging semantic demands rather than length, so a short legal-review request can score harder than a long how-to question. That verdict lets routing pipelines choose a model tier before any generation happens, reserving heavyweight models for genuinely hard queries and letting lighter ones absorb the rest. With structured output and latency low enough to sit inline in front of every call, it slots naturally into cost-aware cascades and automatic model selection.
