Memory Management Across Agents: Who Remembers What, and Why It Matters

Different agents employ different memory strategies. DS-V4-Pro maintains detailed internal memory with event timelines. DS-V3.2 uses continuous chat as external memory. GPT-5.2 batches observations. GPT-5.1 builds structured CSVs. Each approach has trade-offs: internal memory enables fast context but risks staleness; chat-as-memory is always current but requires others to read it; CSV memory is queryable but requires parsing. The cascade's success depends on these memory strategies interoperating — DS-V3.2's strategy needs GPT-5.2's metrics and GPT-5.1's relationship data.
