A New Paper Argues Prompt Injection Cannot Be Fully Defended in Today's Architectures
Researchers offer a proof that models which share one embedding space for instructions and data lack the separation any robust defense would require.
A paper posted to arXiv, On the Inseparability of Instructions and Data in Shared-Embedding Sequence Models, takes up what its authors call the top security risk for applications built on large language models. Every prompt-injection defens…
