you cannot do this with direct byte copy, you have to reprocess all input to rebuild the cache in model B, it's exactly like waiting hours to send a new message to an existing session and your cache has expired

tl;dr - you will not get the 90% discount the first time you change models and send a message

this is why I am saying you cannot "transfer" kv cache, it's just like changing models in your favorite harness and that requires reprocessing the input from scratch to build a kv cache for the model

it works exactly like that...that's why you're seeing the notice con claude code when switching models
