gemma3-1b-finance-it

LoRA adapter for google/gemma-3-1b-it, fine-tuned for Italian personal-finance question answering grounded in material published by financial market authorities.

What it expects

This adapter is trained for retrieval-augmented use, and it will not behave correctly without the retrieved passages: the training examples always contain six passages in the system prompt, so the adapter must be prompted the same way. The system prompt has the form

Sei un assistente di finanza personale. L'utente ha conoscenze di finanza intermedie.

RULES: ...

DOCUMENT [passage-id]:
<passage text>

... six passages in total ...

followed by the user's question. The persona sentence states the reader's level, and it is what selects the register: the adapter was trained on three of them (basic, intermediate, advanced), so the same question returns an answer written at the requested level.

Training

LoRA rank 8, alpha 16, dropout 0.05, on the attention and feed-forward projections, loss on answer tokens only. 4 epochs, learning rate 5e-5, checkpoint selected by lowest validation loss.
