 # Transformer XL
 
+<Tip warning={true}>
+
+This model is in maintenance mode only, so we won't accept any new PRs changing its code. This model was deprecated due to security issues linked to `pickle.load`.
+
+We recommend switching to more recent models for improved security.
+
+In case you would still like to use `TransfoXL` in your experiments, we recommend using the [Hub checkpoint](https://huggingface.co/transfo-xl-wt103) with a specific revision to ensure you are downloading safe files from the Hub:
+
+```
+from transformers import TransfoXLTokenizer, TransfoXLLMHeadModel
+
+checkpoint = 'transfo-xl-wt103'
+revision = '40a186da79458c9f9de846edfaea79c412137f97'
+
+tokenizer = TransfoXLTokenizer.from_pretrained(checkpoint, revision=revision)
+model = TransfoXLLMHeadModel.from_pretrained(checkpoint, revision=revision)
+```
+
+If you run into any issues running this model, please reinstall the last version that supported this model: v4.35.0.
+You can do so by running the following command: `pip install -U transformers==4.35.0`.
+
+</Tip>
