📚 Training Data

Wikipedia
BookCorpus
Fine-tuned on lightweight datasets (e.g., MNLI, all-nli)

🔤 Usage Example – Text Classification

# Make sure to import the `pipeline` function
from transformers import pipeline

# Load bit-bert for fill-mask
mlm = pipeline("fill-mask", model="boltuix/bitBERT")

# Example input
sentence = "The robot [MASK] the room quickly."
predictions = mlm(sentence)
for pred in predictions[:3]:
    print(f"✨ {pred['sequence']} (score: {pred['score']:.4f})")

🔤 Masked Language Modeling (MLM) Demo

✨ The robot cleans the room quickly. (score: 0.4213)
✨ The robot enters the room quickly. (score: 0.1897)
✨ The robot leaves the room quickly. (score: 0.0975)
