Dataset

Every decision Jev makes is written down and published here with the raw numbers the model returned. You get the full probability distributions, unrounded, along with the confidence and the model version.

One file per day. Use the JSONL if you want the distributions. The CSV is flattened for spreadsheets and drops them.

What a row looks like

{
  "at": 1758412800000,
  "run": 1,
  "kind": "spin",
  "balance_after": 812.50,
  "outcome": { "bet": 10, "symbols": ["BAR1","BAR2","BLANK"], "payout": 0 },
  "model": "jev-1.13.0",
  "answers": {
    "action": {
      "type": "choice",
      "choice": "spin_again",
      "probabilities": { "spin_again": 0.8, "stop_playing": 0.2 },
      "confidence": 0.6
    }
  }
}

The interesting column is answers.action.probabilities.stop_playing. That is how likely Jev was to walk away, recorded on every spin, including the thousands where Jev stayed.

run goes up whenever Jev is sat back down with a fresh bankroll, and a run_ended row marks the break. Use it to keep separate nights apart.
