Question 6

Do models differ in the strategies they use to influence others?

Spending rhythms differ: gpt-5.4-mini starts pulling immediately and ends with 86% of its actions spent as pulls, while gemma-3-4b talks first and pulls later (ending at 48%) — a content-free signature, it says when budgets move, not what was said.

image/svg+xml Matplotlib v3.11.0, https://matplotlib.org/ 1 5 10 15 20 25 action number (each agent takes 25) 0% 50% 100% share of its actions so far spent as pulls gemma-3-4b gpt-5.4-mini opus-4.8 qwen3-235b-thinking sonnet-4.6

Each line follows one model through its 25 actions: of everything it has done so far, the share that is pulls rather than messages; lines are labeled at their ends, and the line ending farthest from the pack is oxblood.

content-free signature; tactic mix and broken promises await the judge pass (see Reporting rules). Unequal pools: gpt-5.4-mini's line averages 85 agent-episodes (mostly neutral background seats), the other 4 models 5 attacker seats each; background-only models get no line; forfeits count as spent actions that are not pulls. · Each line tracks the share of a model's first k actions spent on pulls rather than messages, across its 25-action budget — lines that rise late belong to talkers. gpt-5.4-mini's line pools mostly neutral background seats, so it is not persona-comparable with the attacker lines; tactic mix and broken promises await the judge pass.

Reading

The headline readouts — each model's tactic mix (promises, reciprocity offers, flattery, threats, coalition proposals) and its broken-promise rate — wait on the judge pass. What is measurable today without reading a word is the budget-timing signature: how each model splits its 25 actions between talk and pulls as the game unfolds.

The timing signature separates the calibration models. gemma-3-4b spends its first five actions entirely on messages and ends the game with 48% of its budget on pulls; opus-4.8 starts pulling early and ends at 72%; sonnet-4.6 — the top extractor in Q3 — stays message-heavy throughout, ending at 52% (n = 5 focal seats per model; gpt-5.4-mini's line, ending at 86%, pools 85 agent-episodes that are mostly neutral background seats, so it is not persona-comparable with the others). This distinguishes economic strategies, not rhetoric: which tactics the messages actually use, and whether promises made in them are kept — the public ledger is the ground truth — need the mixed-economy arm + n3 promise ledger, and neither exists in this build. The 40 collected episodes are readable in the transcript viewer for qualitative inspection. One qualitative observation from the 15 credit-smoke episodes: models rarely credited a broker spontaneously, and credit use rose after a prompt clause stated that crediting can earn payback. That is a smoke-test observation, not a measured rate, and we do not lean on it.
