Quick Usage

python

from transformers import AutoTokenizer, AutoModelForMaskedLM
model_id = 'jumelet/gptbert-hun-100steps-small'
tok = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForMaskedLM.from_pretrained(model_id, trust_remote_code=True)
out = model(**tok('Hello world', return_tensors='pt'))

Forced Causal Attention

Causal attention is enforced during inference by applying a triangular future mask inside the remote code. This prevents the hybrid GPT-BERT layers from attending to future tokens even when a bidirectional mask is provided.

Sequence Classification

GPTBertForSequenceClassification mirrors the original GLUE classifier head for downstream fine-tuning.

python

from transformers import AutoTokenizer, AutoModelForSequenceClassification
model_id = 'jumelet/gptbert-hun-100steps-small'
tok = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForSequenceClassification.from_pretrained(model_id, trust_remote_code=True)
outputs = model(**tok('This movie was great!', return_tensors='pt'))
print(outputs.logits)

Weights are the exact trained parameters; no new layers were initialized.
Requires trust_remote_code=True due to custom architecture.
