# Researchers Propose Catching Insecure Code From Model Activations Before It Is Written

The method probes latent activations during prefill rather than screening finished output with static analyzers or a judge model.

A preprint titled Probing the Prefill addresses a structural weakness in how teams secure AI-generated code. Current defenses act only after the fact. A static analyzer, a fine-tuned classifier or a separate judge model inspects the finishe…
