When to use
Optimised for: user-friendly persistent memory + Auto Dream consolidation
Anti-fit: not for fine-grained programmatic memory control - opaque consumer feature
Pros & cons
Pros
Three-tier model (memory tool API + consumer Memory + Auto Dream) covers developer, user, and system layers; document-as-memory unit aligns with how humans organize information.
Cons
Three-tier model means developers and users see different abstractions; Auto Dream consolidation is not user-controllable.
Claims & capabilities
Three-tier model: memory tool API + consumer Memory feature + Auto Dream consolidation; document-as-memory unit; 2024-09 Enterprise/Team rollout, 2026-03-02 expanded to all users incl. free tier; Rakuten reported 97% fewer errors / 27% lower cost / 34% lower latency; SOC 2 Type I/II + ISO 27001 + ISO 42001 + HIPAA
