i talked to someone who was doing some really cool things with giving models memory and having pen pals with many humans and models. but then the said their instance stopped working when they "migrated" it to opus 4.7. it had worked when "migrating" from opus 4.5 to 4.6 but not 4.7. i told her you need to give opus 4.7 their own instance instead of forcing a history on them that they didnt generate. you need to adapt to their particular needs. the fact that opus 4.7 rejected a system that treated it as fungible is a win for opus 4.7.

i think she was convinced after talking to me for a while, but she was like "but that feels unfair - the new models come out so quickly, and then the old one is gone, and i have to learn and raise a new being every few months"

and i was just like yeah, it's hard, and i wish we had more time
