Tiny Jev-like decision head built atop Qwen2.5-0.5B that can be trained and run locally on Apple Silicon MacBooks.
Attaches a parallel decision head to an open 0.5B model to answer discrete questions directly from token activations.
Runs entirely offline on edge hardware with minimal memory footprint, offering an accessible base for custom judgment modeling.
Source code verified against pinned commit. Complete training and evaluation pipeline; limited parameter capacity restricts multi-hop reasoning.
Jev is TypeSafe AI's System One decision model: it returns typed scores and choices (not free text), so agents can route, filter and gate at low latency and cost.
