896 dims · 8 J-space directions · drag-free rotation
Explore the reasoning workspace
These 8 directions carry 76% of the model's pull on its next words — the J-space. Each row is one direction and its share of the workspace. Swap one for a random direction and watch reasoning integrity fall — J-directions cost about 2× more than random ones.
reasoning integrity · illustrative100%
Nothing swapped — the workspace is intact.
Terms & theory are a best-effort read of a 0.5B model — at this scale the directions are mostly word-piece fragments, not clean concepts (clean per-direction meaning needs a much bigger model, as Anthropic used). The energy share and the 2× causal effect are the solid parts.
