Open-Source Jev Alternatives and Reproductions

Jev's weights are not public, but the interface is: a state and typed questions in, probabilities out, in one forward pass. These projects reproduce that interface on open models, from a 0.6B model trained from scratch to a Jev-compatible API server.

They are useful for self-hosting, for understanding how System One models work, and as a baseline when evaluating Jev.
