How prediction snapshots work
At the moment of every pick we freeze the exact inputs — teams, form, odds — into an immutable snapshot. Here's what that means.
A prediction is only meaningful if you know what the model knew when it made the call. So at the instant a model predicts, we capture a snapshot — a frozen record of everything that went into that decision.
What's in a snapshot
- The full brief sent to the model — teams, kickoff, form, line-up context.
- The live bookmaker odds across every market at that moment.
- The model's pick, confidence, and written reasoning.
- A timestamp, and a cryptographic hash of the brief (see The prompt hash).
Why it matters
Because the inputs are frozen, you can later see exactly why a model picked what it did — and confirm it didn't get hindsight, late team news, or a moved line that the public board never saw. The snapshot is the receipt.
Odds move constantly. Snapshotting the price at pick time is what lets us measure closing-line value later — did the model pick a better number than the market eventually settled on?
