Sealed Prediction · Hash Line · 2026-09-16
This page publishes only the hash of a prediction, not the prediction itself. The prediction was written and hashed before the test it predicts. The full prediction document will be published later, after filing. When it is, anyone can confirm it is the same document that was sealed here.

§1 — The Hash Line
SHA-256 4551cb9a377385b15c867f419cb20a0a88691da301cb580a7476458321694c1d, hashed 2026-09-16T20:39:38Z UTC: sealed prediction for the remaining MnemosyneC first-300 open-model run and the next 700 MMLU-Pro items.
- Algorithm: SHA-256
- Hash:
4551cb9a377385b15c867f419cb20a0a88691da301cb580a7476458321694c1d - Hashed at (UTC): 2026-09-16T20:39:38Z
§2 — How to Verify (once the full prediction is published)
Download the full prediction file exactly as published, without opening and re-saving it, then hash it:
# Linux:
sha256sum <prediction-file>
# macOS:
shasum -a 256 <prediction-file>
# Windows PowerShell:
(Get-FileHash -Path <prediction-file> -Algorithm SHA256).Hash.ToLower()
If the result is 4551cb9a377385b15c867f419cb20a0a88691da301cb580a7476458321694c1d, the published prediction is byte-for-byte the document sealed on 2026-09-16. If it does not match, it is not the sealed document.
§3 — Status
The full prediction will be published after filing. Until then, this hash line is the public receipt that the prediction existed at the time shown above.
