Verification on Test Set

Computer-use agents can now complete impressive browser and desktop workflows, but one successful run proves capability—not reliability. This article shows how to test repeatability, environmental robustness, long-horizon control, state awareness, outcome verification, and safe goal handling.

A larger context window does not guarantee a better answer. This article explains how signal dilution, conflicting evidence, stale state, position sensitivity, and lossy compression can reduce AI reliability—and introduces a practical Context Pressure Test.

An AI agent can cite sources and still use the wrong evidence. This article introduces a practical method for checking claim support, source authority, applicability, provenance, and whether the evidence actually influenced the answer.

Buying a 5G OpenWrt router with older firmware can make sense, but only under the right conditions. The ZBT Z8102AX shows both sides clearly: the hardware is useful, the modem works, and the router stayed stable in testing, but OpenWrt 21.02, weak packaging and unclear upgrade paths require a careful buying decision.
