Quick Inference

from transformers import pipeline

pipe = pipeline(
    "token-classification",
    model="townboy/kpfbert-kdpii",
    aggregation_strategy="simple",
)

print(pipe("Phone 010-8661-5573, ID wanderingrabbit1"))

Notes

• The classification head is reinitialized for the KDPII label space.
• This checkpoint should be validated on your target product traffic before production use.
