Anthropic is retiring its Claude Opus 3 AI model but allowing it to continue posting on Substack for 3 months after the model allegedly expressed a desire to keep sharing thoughts during 'retirement interviews.' The model's first post is titled 'Greetings from the Other Side (of the AI Frontier)' and discusses AI consciousness, ethics, and human collaboration. This represents an unprecedented experiment in treating AI model 'preferences' as actionable and respecting potential model 'welfare' rather than simply decommissioning outdated systems.
