Quick Start

from transformers import AutoTokenizer, AutoModelForSequenceClassification
from peft import PeftModel

base = AutoModelForSequenceClassification.from_pretrained(
          "HuggingFaceTB/SmolLM2-135M-Instruct", num_labels=2)
model = PeftModel.from_pretrained(base, "marc-es/orga-dynamic-1")
tok   = AutoTokenizer.from_pretrained("marc-es/orga-dynamic-1")

def is_end(text):
    out = model(**tok(text, return_tensors="pt"))[0]
    return out.argmax(-1).item() == 1   # True = EOU
