Quick Start

python

from sentence_transformers import SentenceTransformer

model = SentenceTransformer("L4_top", trust_remote_code=True)

sentences = [
    "Hello, how are you?",
    "안녕하세요",
    "Bonjour, comment allez-vous?",
]

embeddings = model.encode(sentences)
print(embeddings.shape)  # (3, 384)
