I wanted to be able to persist Entity Memory in a Redis database, so I abstracted
ConversationEntityMemoryto allow for pluggable Entity stores (d06f90d).Then I implemented a Entity store that... erm... stores Entities in Redis. By default, Entities will expire from memory after 24 hours, but they'll be persisted for another 3 days every time they're recalled. The idea is to give the AIs a bit of a spaced-repetition memory, but I have yet to see if this is useful. The memory is partitioned by
session_id(user ID? chat channel? whatever, really) so entities from one user don't leak to another.While developing this, I did notice that the Entity summaries are kind of buggy (they summarize AI-generated content and not just information the human gave them, sometimes they add things like "No new information provided. Existing summary remains: As stated previously, X", etc.), but I'll tackle that later. First I wanted to get some input on this idea.
