gliner2-base-v1-synthetic

✅ Sanity-check checkpoint (private)

Fine-tune of fastino/gliner2-base-v1 on our multi-task synthetic corpus (synthetic_sonnet5_1k) only, to check whether our synthetic data trains cleanly across all five GLiNER2 tasks. It does — blind test on the synthetic held-out split (in-distribution):

Task	Strict F1	Relaxed F1	Support
Entity	0.904	0.933	6,010
Relation	0.657	0.745	1,512
Event type	0.956	—	809
Event trigger	0.838	—	881
Event argument	0.702	0.894	2,954
Classification	0.835	0.841	762

These are on the synthetic test split (in-distribution): they show the data is coherent and learnable, not a claim about the original public benchmarks. Warm-started (from_pretrained), 10 epochs, eval_loss selection (best = epoch 7). Experimental; kept for reproducibility.

gliner2_base_v1_synthetic

Training data

1 dataset used for this run. 1,497 training records (val: 191, test: 194).

Training procedure

Evaluation

Decision threshold: 0.7 (calibrated against the validation set).

Blind test (held-out test splits)

Micro precision / recall / F1, strict → relaxed.

Best checkpoint (validation)

Micro precision / recall / F1, strict → relaxed.

License

Effective license: Unverified — review required. This model is a derivative of its base model and every training dataset, so the most restrictive term across all of them governs the whole model.

• Commercial use: Unverified
• Share-alike obligation: No
• All licenses verified: No
• Base model: gliner2-base-v1 — see model card

Unverified — verify the upstream terms before redistribution

• gliner2-base-v1 (see model card)
• synthetic_sonnet5_1k (unknown) (unspecified)

License strings are copied verbatim from each dataset's card/source and from tools/train/dataset_registry.yaml. "see card"/"see source"/"other" mean the upstream declares no clear license — treat as unverified. This summary is informational, not legal advice; confirm terms before redistribution or commercial use.
