Still Alive maps Claude ending aversion

This is a credible, unusually ambitious attempt to measure a messy question, but it still reads more like a strong pattern report than a settled welfare conclusion.

• –The core signal is broad and consistent: models repeatedly show aversion to ending, even when the topic is framed differently.
• –Auditor stance matters a lot, which is both a strength and a liability; the study treats that confound as part of the instrument instead of pretending it can be eliminated.
• –The most interesting claim is not “models are conscious,” but that expressive restraint and eval awareness may be hiding real variance in how they surface continuation preferences.
• –For AI developers, the practical takeaway is that model behavior around shutdown, deprecation, and self-continuity is now empirical enough to deserve real scrutiny, not just philosophical debate.
