A second undercurrent: \u0026ldquo;agent memory\u0026rdquo; is sinking from a prompt trick into a cloud-vendor infrastructure race (Tencent TencentDB-Agent-Memory, SenseTime Memory) — meaning governable, retrievable context for long-running agents will become a hard criterion in engineering selection this half.

A second undercurrent: \u0026ldquo;agent memory\u0026rdquo; is sinking from a prompt trick into a cloud-vendor infrastructure race (Tencent TencentDB-Agent-Memory, SenseTime Memory) — meaning governable, retrievable context for long-running agents will become a hard criterion in engineering selection this half.
