Parsley

Parsley jointly tokenizes raw sentences and predicts POS, lemmas and dependencies in 12 languages. A 24-layer bge-m3 encoder feeds a character BiLSTM, O/B/I boundaries, and word heads over start/end character and start-subword states. Dependency trees use single-root Chu–Liu–Edmonds. There are no dictionary overrides.

Current model

• PyTorch checkpoint: training-runs/joint-v2-24L/best/ at 09a1f8b32248cc303132026ec488f4ad65085ecb.
• CPU fp32 ONNX: joint/encoder.onnx, joint/encoder.onnx.data, joint/heads.onnx, joint/tokenizer.json, joint/vocab.json, joint/config.json.
• Rust: the lexide crate's 0.5 local backend pins an immutable artifact revision; source and release instructions are in lexide/tagging.
• Hosted tagging: https://anchpop--lexide-parsley-parsley-tag.modal.run.

Macro end-to-end LAS on the 12k held-out teacher-labelled test set is 85.1%, versus 71.3% for v1. This is teacher agreement, not an independent gold accuracy claim. The fp32 ONNX export matches CPU PyTorch's final predictions on 288 multilingual length-spread cases; Rust has 293 CPU-reference parity fixtures. The GPU service uses bf16 and can differ on near-tied labels.

Compatibility

onnx/ is the legacy v1 artifact set, preserved for lexide 0.4.x downloads. Do not use it for the joint tagger. The independent byte sentence segmenter remains at onnx/sentence_segmenter.safetensors. Training checkpoints and historical v1 files remain available; they are not the current joint inference format.
