+# Model Overview
+
+## Description
+
+This model performs visual feature extraction.
+For instance, RADIO generates image embeddings that can be used by a downstream model to classify images.
+
+C-RADIOv2 models are available in multiple sizes:
+* Base (90M parameters).
+* Large (320M parameters).
+* Huge (653M parameters).
+* Gigantic (1.8B parameters).
+
+C-RADIOv2 was trained for 1M steps (400k more steps than v1), using inverse frequency sampling for data balancing, and [PHI Standardization](https://arxiv.org/abs/2410.01680) for teacher distribution balancing.
+
+This model is ready for commercial/non-commercial use.
+

Additionally, the generated embeddings might fail to disambiguate differences that appear evident to humans (e.g. two images showing different breeds of dogs might in fact produce very similar embeddings). Domain-specific evaluation is required for the target application.
