system-one-gemma

Open-source Jev-style System One decision model. Gemma 3 270M with a scoring head, fast, calibrated decisions in a single forward pass. No text generation. Inspired by TypeSafe.ai's Jev.

Numbers, harnesses, and comparisons you can rerun on your hardware instead of trusting a screenshot. Tags in the wild: benchmarks, eval. The repo has install steps, env vars, and recent commits if you are deciding whether to depend on it.
