It can support continuity, but does not guarantee learning or factual correctness.
Research systems such as Generative Agents use a memory stream, retrieval, reflection, and planning in a simulated-agent setting. Reflexion stores textual lessons from feedback for later attempts without changing model weights. These are research designs, not evidence that every memory system learns preferences correctly. Memory may be stale, irrelevant, or sensitive, so storage and retrieval need explicit policies. In the Generative Agents paper, each memory object contains a natural-language description, creation timestamp, and most-recent-access timestamp. Its retrieval score combines recency, relevance, and importance. These are properties of that paper’s implementation, not every agent-memory system. User-facing inspection, correction, and deletion are useful design controls for systems that retain personal facts. A useful classical distinction is semantic memory for general facts and learned knowledge versus episodic memory for personally experienced events situated in time and context. An agent memory design may represent both, but the labels describe different content and do not guarantee truth or permanence.
Store a user-approved preference with its source and timestamp.
Retrieve project notes relevant to a new coding task.
Summarize repeated observations while preserving links to original records.
Let users inspect or delete stored information.
Memory APIs and agent systems are evolving. Evaluate retrieval quality, privacy, and stale-fact handling for the target application; do not treat retrieved text as verified truth.

Agent memory stores selected information outside a model’s current context and retrieves it when useful. It can support continuity, but does not guarantee learning or factual correctness.
For a stateless request, information not present in the current context is unavailable unless an application stores and retrieves it. This does not mean every model or application handles memory the same way.
Memori semantik menyimpan fakta dan preferensi umum, sedangkan memori episodik menyimpan catatan peristiwa masa lalu yang spesifik.
The Generative Agents paper describes each memory object as having a natural-language description, a creation timestamp, and a most-recent-access timestamp.
Penyimpanannya murah; tantangannya adalah memilih, merangkum, mendapatkan kembali ingatan yang tepat, dan melupakan informasi yang basi atau kontradiktif.
Refleksi menggabungkan log interaksi mentah ke dalam wawasan semantik tingkat tinggi yang dapat digunakan kembali oleh agen, seperti yang terlihat dalam desain agen generatif.
