 ## Performance
 
-The model was evaluated on a benchmark collected from the same datasets used for training, alongside a closed subset of SuperAnnotate. \
-However, there are no direct intersections of samples between the training data and the benchmark. \
+The model was evaluated on a benchmark consisting of a holdout subset of training data, alongside a closed subset of SuperAnnotate data. \
 The benchmark comprises 1k samples, with 200 samples per category. \
 The model's performance is compared with open-source solutions and popular API detectors in the table below:
