Meta 测试 AI 穿搭应用 Style Sketch，泰国在首批测试市场之列

The deferral-first training trick is the transferable idea: rather than letting an agent freely rewrite rankings, PAMO rewards overrides only when they preserve accuracy. Developers building recommendation or agent systems can apply the same counterfactual masking to any cross-context personalisation task. It also frames the privacy tension of pooling history across apps, a question regulators and platform teams will face as personal agents spread.

The key insight is that memory design, not memory size, is the bottleneck: a single global history barely helps interleaved workloads, while clustering trajectories delivers double-digit reward gains at lower cost. Teams building agents for mixed task streams can try splitting memory into clusters before investing in larger memory systems. One open question the paper leaves untested is whether parallel agents can safely update a shared cluster.
