What Are Model Weights?

01

Neural Network Parameters Weights are the learned parameters that define how an AI model processes information
02

Valuable Intellectual Property Training large models costs millions in compute resources and proprietary data
03

The Crown Jewels Stolen weights enable replication of powerful models without the original training investment
04

Growing Attack Surface As models grow larger, the security of weights becomes increasingly critical

03

The Attack Vector

How weights can be extracted from deployed models
