+## YoloX model
+
+For using the YoloX model the endpoints are: 
+```
+http://localhost:8000/layout_v1/pdf
+http://localhost:8000/layout_v1/image
+```
+For example:
+```
+curl -X 'POST' 'http://localhost:8000/layout/yolox/image' \
+-F 'file=@sample-docs/test-image.jpg' \
+ | jq -C | less -R
+
+curl -X 'POST' 'http://localhost:8000/layout/yolox/pdf' \
+-F 'file=@sample-docs/loremipsum.pdf' \
+ | jq -C | less -R
+```
+
+If your PDF file doesn't have text embedded you can force the use of OCR with
+the parameter force_ocr=True:
+```
+curl -X 'POST' 'http://localhost:8000/layout/yolox/pdf' \
+-F 'file=@sample-docs/loremipsum.pdf' \
+-F force_ocr=true 
+ | jq -C | less -R
+```
+
+or in local:
+
+```
+layout = yolox_local_inference(filename, type="pdf")
+```
