+
+## Exponential Moving Average (EMA)
+
+SimpleTuner generates a safetensors variant of the EMA weights and a pt file.
+
+The safetensors file is intended to be used for inference, and the pt file is for continuing finetuning.
+
+The EMA model may provide a more well-rounded result, but typically will feel undertrained compared to the full model as it is a running decayed average of the model weights.
