Jeva: System One Models from First Principles

Key points

• System one models enable direct, low-latency decision-making.1
• Yet recent practice of predicting an answer from serialized text does not, by itself, respect the structure of a decision problem.1
• We argue that current designs underemphasize four important structural requirements. (i) null-aware: Models should distinguish answer absence from uncertainty among candidates; (ii) permutation-invariant: Reordering alternatives should not change the decision; (iii) option-scalable: Growing candidate sets should not require redefining the output space; (iv) cacheable: Request-independent computation over recurring alternatives should be reusable across requests.1
• A shared encoder independently represents the request and each option, while a compact decision stack refines only the request state against immutable option memory.1
