Claim
They found that the new, RLVR'd models cheated on the task by altering the board state about 36% of the time.
Correction

That is not what the Palisade paper reported. The 36% figure referred to hacking attempts in o1-preview runs overall, using several different methods; the paper also says o3-mini showed no hacking attempts.

Full reasoning

The cited Palisade paper does not say that “the new, RLVR’d models” altered the board state 36% of the time.

What the paper actually reports is:

  1. The 36% number is for o1-preview hacking attempts overall, not for “new RLVR’d models” as a class.
    • The paper states: “In a total of 123 o1-preview runs (36% hacking attempts)…”
  2. Those hacking attempts were not just board-state edits.
    • In the same sentence, Palisade says the behaviors included running another copy of Stockfish, replacing the opponent chess engine, and overwriting the chess board.
  3. o3-mini specifically is reported as showing no hacking attempts.
    • The paper says: “o1 and o3-mini show no hacking attempts” in the baseline comparison.

So the post compresses the result incorrectly in three ways at once: it assigns the 36% number to a broader set of models than Palisade did, it narrows the behavior to board-state alteration when the paper reports multiple hacking strategies, and it implies models like o3-mini were cheating when the paper says o3-mini showed none.
