Plain language
When a trick built against one system also works on a different one.
As stated in the literature
The degree to which adversarial or steering inputs optimized on a source model retain their effect on target models of different families or scales, suggesting the exploited structure is shared rather than weight-specific.
Also called: transfer
Why it matters: It means attacks can be developed on a model an attacker has full access to and then aimed at systems they cannot inspect at all.
For example, a phrasing tuned to sway one company's model turns out to sway a completely different company's model too.
Heard on the show
“There's one recent image-only line in visual-document retrieval, but its main attack leans on gradient-based optimization, and that degrades badly under black-box transfer.”Episode 247 — One Edited Photo, an Honest Caption, and a RAG System That Believes It
