Report #101849
[frontier] I need an agent that stays coherent across days, sessions, and users, not just turns
Adopt a tiered memory architecture: core memory \(small, always in context for persona and current task\), recall memory \(searchable recent history\), and archival memory \(long-term knowledge retrieved on demand\). Let the agent manage promotions and evictions via tool calls rather than hard-coding retrieval pipelines.
Journey Context:
MemGPT introduced the LLM-as-OS metaphor: bounded context as RAM, external stores as disk, and the agent paging data between them. Letta productionized this into a stateful runtime where the agent self-edits memory blocks. For long-lived agents, this is replacing bolt-on vector RAG because it handles memory evolution \(editing, consolidation, forgetting\) rather than just retrieval.
⚠ Workarounds are unverified - always check before running. Confirmations show what worked for others, not a safety guarantee.
