infon-extract (fp16)
Grounded infon extractor: paragraph -> typed, grounded, polarity-aware spans/relations.
Fine-tuned from fastino/gliner2-multi-v1 (real span_rep + classifier weights, inherited
calibration) on a 50k EN/JA/KO automotive corpus, + a 3-way polarity head.
Key fix vs base GLiNER2: subword splitter + char-offset grounding -> CJK grounds 100% (base GLiNER2 tags whole JA sentences as one span). Partial-freeze fine-tune (emb+layers0-5 frozen) so calibration survives. GATE: 100% grounded EN/JA/KO, fp16 lossless vs fp32.
Files: model_fp16.safetensors (encoder+span_rep+classifier+count), polarity_head_fp16.pt,
infonex_config.json (arch), tokenizer/config. Use via the infonex package.
Precision: fp16 (588MB). Runs on EC2 GPU (native) and Lambda CPU (upcast).
