01 / THE MODEL
A model for structured decisions
JEV is TypeSafe AI’s System One model. Given context and predefined questions, it returns typed choices, scores and probabilities. TypeSafe describes its training approach as Reinforcement Learning for Calibrated Decisions (RLCD). [1]
STATEMarket context→JEV→CHOICEDirection + probabilities
Visible uncertainty
Probabilities and confidence help reveal whether a view is clearly favored.
Defined responsibilities
Code computes indicators; JEV evaluates the supplied evidence against defined criteria.
How do we use it for event contract analysis?⌄

02Indicators + depth + trades
03JEV directional classification
04Evidence + observation guidance
This is our product design rationale: organize multiple technical signals into a reviewable directional view. Inputs currently describe spot markets. A candle interval is a data resolution, not a contract expiry. The request does not bind a specific contract strike, settlement rule or payout, so its output is technical context.
JEV does not generate free-form reports. The application organizes evidence and maps selected actions to predefined guidance; these are not the model’s internal reasoning. [3]
Where does confidence come from?⌄
02 / READING UNCERTAINTY
Distribution → concentration → confidence
The official guide describes confidence as a 0–1 statistic derived from the Choice or Score probability distribution. Concentrated distributions indicate clearer decisions. The guide does not disclose the exact formula; neither entropy nor the largest probability should be presented as that formula. [2]
We display the direction answer’s confidence × 100%, or “—” when absent. Confidence in a separate score answer and the largest directional probability are different quantities.

Spread across multiple directions
Distribution shapes only; no JEV confidence value is inferred.Why use JEV for event contract technical analysis?⌄
Fast-moving BTC and ETH markets demand attention to trend, momentum and buying and selling pressure. We integrate JEV into a technical analysis workflow that combines candles, volume, depth and recent trades in one assessment. Five directional categories, probabilities and confidence make it easier to see whether signals align and focus your attention on timing and decisions.
Model level
Official limitations include numerical precision and complex indirection. Compute indicators in code and define precise classification criteria. [3]
Financial evaluation
Fix prediction times, expiry rules and settlement prices, then evaluate out of sample against baselines, calibration curves and Brier scores, including costs and payouts. Such results are not yet reported here.
Directional confidence describes certainty in a classification. An 80% value does not establish an 80% contract win probability or historical win rate.
