Yes. This means you can 'ask' up to 15,000 times a month. Writes are (for that tier) capped at 2500 a month.

Example, after an hour long AI session, you can 'save to my vault' and it will extrapolate the session as one context/learning, or all the valid bits as individual records at your discretion. This constitutes saving memories, of which you get 2500 a month. Later, if you ask "have we done something like this before?", that is 1 query to the vault.

We're open to shifting these limits around based on actual usage and fairness. 15k a month seemed like a high ceiling to us, but perhaps for some orgs they would reach that much faster. Open to suggestions. The designed intent was you saved what you thought was valuable enough to save for recall later, not everything from every AI session.
