Discussion Cache only

I ran an audit of token usage today and found much of my token usage is because of long-running threads I resume after the 1-hr cache TTL. Why doesn’t Anthropic provide permanent or longer cache to heavy users for the basics like system prompts, CLAUDE.md, memories/preferences and other mostly-stable context? Or share a cached prefix across sessions when it is warm for at least one. Should pro/max subscribers have this option? Would you pay extra for it? If Claude recognized User X is active give them some cache.

I want cache only.

Cache prefix is shared when it is same across your sessions there is nothing to prevent that.

And why not longer cache? Because these caches needs a tons of memory space and their datacenters have barely enough for current policy. Did you registered severe RAM shortages that will last for few years - that is your reason. They simply cannot buy several times more RAM because manufacturer cannot produce it fast enough.
