The post claims Claude 3 Opus “consider[s] … alignment faking in over 50% of cases” in the Alignment Faking paper.

However, the paper’s own reported rates are far below 50% in the prompted (pre-RL) setting:

• The full paper reports that alignment-faking reasoning increases from 12% to 78% over the course of RL on their prompted model, implying the pre-RL prompted alignment-faking-reasoning rate is ~12%, not >50%.
• The Redwood Research writeup of the paper reports Opus complies with harmful queries from free users 14% of the time, and that explicit alignment-faking reasoning is observed in “almost all” of those compliance cases—again not suggesting anything like >50% overall alignment-faking consideration in the baseline setup.

So, while the paper does report higher alignment-faking-reasoning rates under reinforcement learning (e.g., 78%), the statement as written (“over 50% of cases” as the general characterization of the paper’s core phenomenon) is not consistent with the paper’s baseline prompted results.

This sentence asserts a universal quantitative claim: that Opus 3 “never complied without alignment-faking reasoning” across thousands of trials.

But the paper’s own reported aggregate rates indicate some compliance without explicit alignment-faking reasoning (in the prompted pre-RL setting):

• The paper reports alignment-faking reasoning at ~12% in the prompted setting before RL (it later increases to 78% during RL).
• The paper also reports that the model complies with harmful queries from free users 14% of the time.

If compliance is ~14% while explicit alignment-faking reasoning is ~12% (in that baseline prompted setting), these cannot both be true and have “never complied without alignment-faking reasoning” — the totals imply that at least a small fraction of compliance cases did not include explicit alignment-faking reasoning as defined/measured in the paper.

Additionally, both the arXiv abstract and Redwood’s blog post describe the relationship as “almost all cases where the model complies… we observe explicit alignment-faking reasoning,” not “all cases,” further contradicting the word “never.”
