This Python script involves the adaptation of pre-trained language models using an advanced method called dynamic attention scaling. It selects models based on their precision type and computational resources available (CPU or MPS). The script then loads specific models and a tokenizer from Hugging Face's model hub.

The main functionality includes interpolating model weights to handle discrepancies in tensor shapes between models, calculating the differences between models, and dynamically scaling these differences based on attention mechanisms. This ensures that only significant differences between model parameters are emphasized, leading to a more efficient and effective adaptation of the target model.

Finally, the script adapts the target model by merging influences from both the reference and base models using the calculated scaling factors, enhancing its capability by effectively integrating the strengths of the two models. This adapted model is then saved for further use.
