Model Extraction uye Kuba Attacks
Model extraction uses query access to a deployed model to train a substitute that imitates some of its behavior.

Pfupiso
Attacks and reported recovery are specific to the model interface, outputs, and experiment.
Kudzika Kwakadzika
A model-extraction attack treats a deployed model as an oracle: an attacker collects input-output pairs and trains a substitute. The 2016 prediction-API paper demonstrates extraction attacks for specific model classes and shows that omitting confidence values does not prevent every attack. A 2024 study, *Stealing Part of a Production Language Model*, recovers an embedding-projection layer up to symmetries: it reports exact projection-matrix extraction for Ada and Babbage for under $20 in queries and estimates under $2,000 for GPT-3.5 Turbo. These results concern that layer and those models, not full checkpoint extraction. DynaMarks is a separate proposal that dynamically changes API responses using secret parameters to watermark surrogate models in its evaluated vision-model settings.
Kuitwa muNyika yeChokwadi
Limit and monitor high-volume queries to a prediction API.
Compare label-only responses with probability-vector responses when reviewing information exposure.
Evaluate a proposed extraction defense on the model class and access pattern it targets.
Treat watermarking as a method-specific defense, not a universal guarantee of ownership.
Ramangwana reKutora Muenzaniso uye Kuba Kurwiswa
Defenses may combine access controls, monitoring, response design, and model-specific watermarking research. Assess each mitigation against the attack setting and model class it was tested on; no single safeguard guarantees that a substitute cannot be trained or identified.
