System One decision engine that accepts typed questions over a state and answers with calibrated probabilities.

PlatformWebfreeglobal

Lev is an open-source 'System One' decision engine that takes typed questions over an application's state and answers with calibrated probabilities in about 100ms, using ModernBERT/mmBERT-based models rather than a full LLM call. It targets developers who need fast, calibrated decision logic embedded in software.
