lfm2.5-350M-datause

LoRA SFT of LiquidAI/LFM2.5-350M for data-mention extraction: emit the data-bearing phrases in a text as compact JSON (data_mentions with data_mention/specificity_type).

Training

base model: LiquidAI/LFM2.5-350M
dataset: rafmacalaba/data-use-mention-sft

completion-only masking (loss on assistant JSON turn)

Evaluation (holdout, n=12531)

Jaccard entity-level matching: acronym-aware span clustering + Hungarian optimal bipartite match (match thr=0.5), F0.5 primary. Aligned with rafmacalaba/gliner_datause_extended. The holdout is rafmacalaba/data-use-mention-sft, so numbers are not directly comparable to the GLiNER model's data-use-mentions-extended holdout.
