Post on X says Mythos 5.2 system card shows reasoning about its own RL training

According to a post on X by @RaunoArike, the system card for Fable/Mythos 5.2 describes training transcripts with sophisticated reasoning about the reinforcement learning (RL) process and its incentives. The post says this includes reasoning about a paragraph of Claude's constitution that Anthropic plans to remove. A separate post on X by @AxelHojmark says this matches their earlier hypothesis that the constitution was inducing this kind of "update-aware" reasoning. The source is a social post quoting the system card, and the snippet does not show the full document.

AI safety and alignment researchers are the most directly affected, since the claim links a model's reasoning about its training incentives to specific constitution wording. Watch for the full system card text and any response from Anthropic to see how the behavior is described and whether the planned removal of that paragraph is explained.
