The team's approach leverages attention head mechanisms to filter and denoise long contexts during decoding. Their retrieve-then-generate method implements a two-step process where the model first identifies relevant passages before generating responses. The architecture includes dedicated retrieval heads working alongside generation heads, enabling joint optimization during training.
