Von 1.1 is the earlier comparison version of the Von family. The non-autoregressive architecture evaluates a state, question, and options in one forward pass and returns a probability distribution over the supplied options. It does not generate a token sequence, so it fits bounded selection, yes-or-no, and rating tasks rather than multi-step answers.
Von 1.2 introduces architecture-level order-invariant evaluation of the options. On the JevBench hard tier, 49.5% of Von 1.1’s answers changed when the option order changed; Von 1.2 reached 0% in the same test. The current model card lists Version 1.3 with unchanged 1.2 weights.
