+# Backbone
+
+A backbone is a model used for feature extraction for higher level computer vision tasks such as object detection and image classification. Transformers provides an [`AutoBackbone`] class for initializing a Transformers backbone from pretrained model weights, and two utility classes:
+
+* [`~backbone_utils.BackboneMixin`] enables initializing a backbone from Transformers or [timm](https://hf.co/docs/timm/index) and includes functions for returning the output features and indices.
+* [`~backbone_utils.BackboneConfigMixin`] sets the output features and indices of the backbone configuration.
+
+[timm](https://hf.co/docs/timm/index) models are loaded with the [`TimmBackbone`] and [`TimmBackboneConfig`] classes.
+
+Backbones are supported for the following models:
+
+* [BEiT](../model_doc/beit)
+* [BiT](../model_doc/bit)
+* [ConvNext](../model_doc/convnext)
+* [ConvNextV2](../model_doc/convnextv2)
+* [DiNAT](../model_doc/dinat)
+* [DINOV2](../model_doc/dinov2)
+* [FocalNet](../model_doc/focalnet)
+* [MaskFormer](../model_doc/maskformer)
+* [NAT](../model_doc/nat)
+* [ResNet](../model_doc/resnet)
+* [Swin Transformer](../model_doc/swin)
+* [Swin Transformer v2](../model_doc/swinv2)
+* [ViTDet](../model_doc/vitdet)
