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

Attacks and reported recovery are specific to the model interface, outputs, and experiment.
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.
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.
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.

Uchimbaji huchukulia muundo uliotumika kama chumba cha ndani: mshambuliaji hukusanya jozi za pato-ingizo na kufunza mfano wa paka ili kuiga tabia, bila kufikia uzani asilia.
Kila vekta kamili ya uwezekano hufichua mengi zaidi kuhusu uso wa uamuzi wa ndani wa modeli kuliko lebo moja, ikimruhusu mvamizi kuunda upya mpaka kwa hoja chache.
Matokeo ya kuzidisha, kwa mfano kurudisha lebo ya juu tu au uwezekano wa duara, hupunguza mawimbi ambayo kila jibu humpa mshambulizi, na hivyo kuongeza gharama ya uchimbaji.
The paper recovers the embedding-projection layer up to symmetries, exactly extracts the projection matrix for Ada and Babbage for under $20, and estimates under $2,000 in queries for GPT-3.5 Turbo.
Mara tu wavamizi wanapokuwa na nakala ya ndani, wanaweza kuichunguza kwa uhuru ili kubuni pembejeo za wapinzani au mashambulizi ya kukwepa ambayo pia yanapumbaza mfumo wa awali uliotumwa.
