Jev Ditches Autoregression: A Model That Only Outputs Structured Decisions
karminski3 · x · 2026-09-18
- Jev abandons the traditional autoregressive architecture and cannot output free-form text — it only makes structured decisions.
- Inputs require a Schema (similar to protobuf/GraphQL), compiled into decision slots; the model emits JSON per slot, so output structure can't break. Example: spam classification returns {"isSpam": true, "probabilities": {"true": 0.982}}.
- Text-only input for now; feed game states (e.g. Slay the Spire) or market data plus an action set, and it can autonomously decide step by step — well suited for agent tasks.
