 - `use_fused_adam`: whether to use Habana's custom AdamW implementation
 - `use_fused_clip_norm`: whether to use Habana's fused gradient norm clipping operator
+- `use_torch_autocast`: whether to use Torch Autocast for managing mixed precision
 
 ## Usage
 
 The model is instantiated the same way as in the Transformers library.
-The only difference is that there are a few new training arguments specific to HPUs.
+The only difference is that there are a few new training arguments specific to HPUs.\
+It is strongly recommended to train this model doing bf16 mixed-precision training for optimal performance and accuracy.
