Open the original- What it measures
- The cost covers the queries sent to the model. It does not include the work of building the matching dataset.
- What it does not show
- The price is the researchers' estimate for the 2023 model and prices change. It shows that extraction is cheap for an attacker, not that anyone has extracted private dictation.
