Usage
from transformers import AutoModelForCausalLM, AutoTokenizer
model_id = "Xiao-Youth/LECTOR-4B"
tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(
model_id,
torch_dtype="auto",
device_map="auto",
)

Intended Use
This model is intended for research on scientific reasoning graph extraction, logic-aware scientific writing, and content-conditional introduction generation.
Limitations
The model may produce incorrect reasoning graphs, unsupported claims, or citation errors. Generated text should be manually checked against the source paper content and references before use.
