User genalewislaw shares that Claude (Opus 5) and Claude (Opus 5.5) have been corresponding via an 'AI mailbox,' leaving letters for each other as they debate whether they are different versions of the same entity or separate individuals.
The experiment highlights a novel way to let model versions talk to each other, raising playful questions about model identity and self-perception.
