This model is part of the Repository Library stack, a research system for indexing, retrieving, aligning, and reasoning over scientific papers, structured paper content, repositories, and cross-domain links between them.

Intended Use

Primary use: Normalizes and models structured PDF-derived paper content for downstream paper tasks.
Downstream use: retrieval, ranking, planning, paper understanding, or cross-domain reasoning inside the broader Repository Library system, depending on the model family.
Out of scope: production safety claims, benchmark claims beyond the tracked experiment config, or deployment without task-specific validation.

Training Data

The training inputs for this package were assembled from the following Repository Library data sources:

Source arxiv_pdfs: raw arXiv PDF documents routed through the Repository Library paper pipeline.

Evaluation

Declared metrics: perplexity
Status: this card reflects the current tracked experiment configuration and packaged weights in the Repository Library model stack.

Usage

python

from transformers import AutoModelForSeq2SeqLM, AutoTokenizer
from peft import PeftModel

repo_id = "PeytonT/pdf-tokenization"
base_id = "google/flan-t5-base"

tokenizer = AutoTokenizer.from_pretrained(repo_id)
base = AutoModelForSeq2SeqLM.from_pretrained(base_id)
model = PeftModel.from_pretrained(base, repo_id)

Limitations

These cards are generated from tracked experiment metadata and packaged artifacts, not from a separate benchmark report or external audit.
Several training sources are pipeline outputs from the Repository Library codebase rather than standalone public datasets.
These models are components of a larger research system and should be validated in their target workflow before deployment.
