HyperStyler (Reddit)

Warning: This model was trained on Reddit posts. Generated text may contain profanity, offensive, or discriminatory language.

HyperStyler model trained on the Reddit (MUD) dataset, from HyperStyler: Low-resource Authorship Style Transfer via Context-aware Style Navigation and Hypernetworks (EMNLP 2026).

Code: https://github.com/JK-SHIN-PG/HyperStyler

Usage

from transformers import AutoModel

model = AutoModel.from_pretrained("JKSHINPG/HyperStyler", trust_remote_code=True).to("cuda")

source = "I really think we should leave early tomorrow to avoid traffic."
target_texts = [  # a few texts by the target author
    "lol yeah that's what i said, nobody listens tho",
    "honestly idk why ppl still use that app",
    "ok fair point but its still overpriced imo",
]
print(model.transfer(source, target_texts))

    abstract = "Low-resource authorship style transfer (LAST) aims to rewrite text into the style of an arbitrary target author using only a few reference examples while preserving the original meaning. Existing methods often struggle to achieve both high style fidelity and semantic preservation because they compress diverse references into a single static author embedding, which averages out context-dependent stylistic variation, and rely on hidden representations for style control, which entangle style with content. We propose HyperStyler, a novel architecture that decouples LAST into style selection and style realization. Stylo-navigator predicts style coordinates by jointly modeling the source context and target-author references, and Stylo-hypernet realizes them via dynamic parameter modulation instead of hidden-state injection. Our experiments on Reddit, Blog, and News datasets demonstrate that HyperStyler consistently outperforms prior methods including LLM-based approaches and generalizes robustly across domains. Notably, HyperStyler achieves superior performance with as few as 2.4{\%} additional parameters over T5-large, while being over 1.8{\texttimes} faster than LLMs at inference."
