Black-Box Inference of LLM Architectural Properties with Restrictive API Access
The paper presents NightVision, an attack technique that infers an LLM's internal structural parameters (such as its hidden dimension) from limited API access alone, namely single-token logits.
Signal — Protecting the intellectual property (IP) of model architectures will become more important, and demands for transparency in model inference will grow.
