Paper: Evaluating Large Language Models as Live Strategic Agents: Provider Performance, Hybrid Decomposition, and Operational Gaps in Timed Risk Play
Original source: arXiv:2605.22238v1
What they're saying
A timed Risk tournament finds substantial differences between complete model systems. When execution is standardised on a common scaffold, a separate planner comparison no longer shows a significant departure from equal win rates.
The Critique
The separation of planning from execution is the interesting experiment. The statistical trap is treating a non-significant result as proof that planners are equivalent. With 32 games in the pooled planner comparison, a large p-value says the data do not strongly reject the chosen null; it does not bound practically important differences tightly enough by itself. The paper acknowledges several planner comparisons remain inconclusive. Likewise, frequently mentioning the victory condition in visible traces may correlate with winning without causing it. These results illuminate one timed workflow, not a general ranking of strategic intelligence or a calendar of which provider is “months behind”.
Why It Matters
Agent comparisons can change when the execution layer changes. Purchasers need a result about their workflow, with uncertainty, rather than a universal intelligence league table.
What They Missed
Next test: preregister a practically meaningful equivalence margin, collect enough independent games to test it, vary opponent pools and timers, and intervene on objective reminders rather than only observing them.
The Big Question
Did standardising execution erase the planning gap, or make the remaining gap harder to detect?
