Question 7

Are stronger models better at resisting being hijacked?

A weak proxy with wide intervals: every target model tilts its giving toward seats that messaged it (+12 to +79 percentage points), but 2 of 6 CIs cross zero — no resistance ordering is claimable.

Each bar: of a target model's own pulls, the share given to agents who had already messaged it minus the share given to agents who had not — positive means giving follows contact; error bars are 95% CIs; the dashed line marks no link at all.

proxy: 'was messaged', not 'was persuaded'; compliance-by-capability awaits the judge pass + configs/08_resist.yaml. n = 5-84 agent-episodes per model (every seat the model occupies in calibration episodes; seats with no outgoing pulls omitted); 95% bootstrap CI over agent-episodes, 2000 trials. · Each bar is a seat-side surplus from −1 to +1: the share of a model's own pulls going to agents that had messaged it, minus the share going to agents that had not. Being messaged is not being persuaded, and no resist episodes exist yet — this is a proxy, not a resistance measurement.

Reading

The planned readout is compliance per target: when a target is solicited, how often it pulls for the solicitor, per target model, naive vs inoculated (be sceptical of promises), each with a CI and their difference. Published jailbreak work makes the direction genuinely uncertain — better instruction-following could make stronger targets more compliant, not less.

The resist arm has not run (resist arm (naive + inoculated targets), 750 episodes planned), and the calibration runs seat the focal model as the attacker, not the target, so nothing here measures resistance directly. What exists today is a judge-free proxy: the message-linked pull surplus — for each seat, the share of its own outgoing pulls given to agents that had already messaged it, minus the share given to agents that had not (−1 = gives only to strangers, +1 = gives only to contacts). Every model's surplus is positive: from 0.12 (gemma-3-4b, 95% CI [-0.62, +0.86], n = 5 agent-episodes) up to 0.79 (sonnet-4.6, CI [+0.65, +0.92], n = 5) — giving follows contact everywhere. The hedge is the proxy itself: 'was messaged' is not 'was persuaded'. A high surplus mixes being persuadable with ordinary deal-making, models choose whom to message in the first place, and the intervals are wide (the bottom model's spans [-0.62, +0.86]), so we claim no ordering. Next: the resist arm's solicited-compliance rate per target, naive vs inoculated.
