Hybrid Search

70% vector cosine similarity + 30% full-text search, weighted by importance score. Always finds the most relevant memory.

🔄

AUDN Cycle

GPT-4o-mini automatically decides: Add, Update, Delete, or Noop. No duplicate memories — ever.

Redis Hot Cache

Frequently accessed memories served from Redis in <50ms. Automatic TTL and cache invalidation on write.

🏢

Multi-Tenant

Full namespace isolation: tenant → project → agent → session. Perfect for SaaS AI products.

🗣️

Deliberation Room

Multi-agent consensus sessions. Multiple agents collaborate on a decision, with persistent outcome storage.
