MJev-Spatial: System One Spatial Intelligence via Native Attention Matching
MJev-Spatial is a System 1 model that unifies spatial intelligence tasks—like choosing an option, estimating a number, or pointing to an image—into one classification framework. It uses the pretrained attention projections from Qwen3.5-4B without adding new parameters to score candidates directly. This approach achieves high performance and significant speedups over traditional autoregressive models.
