🔤 Try It: Masked Language Model Demo
Load boltuix/bitBERT and see it in action for masked token prediction.
from transformers import pipeline
mlm = pipeline("fill-mask", model="boltuix/bitBERT")
sentence = "The robot [MASK] the room quickly."
predictions = mlm(sentence)
for pred in predictions[:3]:
print(f"✨ {pred['sequence']} (score: {pred['score']:.4f})")
Example Output:
- ✨ 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)
