Model Description

This Memory Decoder model is trained on the Law domain and can be adapted to enhance any model in the Llama3, Llama3.1, and Llama3.2 families.

[!IMPORTANT] These Llama models are initialized from Qwen models with the embedding layer adapted to fit the Llama tokenizer. This enables efficient cross-model family knowledge transfer.
