Model Overview

Model Summary

Multilingual E5 is a family of multilingual text embedding models from intfloat , based on the XLM-RoBERTa architecture. These models generate fixed-size sentence embeddings suitable for semantic search, retrieval, clustering, and text classification across 100+ languages.

The E5 models were introduced in "Multilingual E5 Text Embeddings: A Technical Report" by Wang et al. The models are trained in two stages: (1) contrastive pre-training on ~1 billion multilingual text pairs, and (2) fine-tuning on labeled datasets. Input text should be prefixed with "query: " or "passage: " for optimal performance.

Key Features:

• Supports 100+ languages via XLM-RoBERTa backbone
• Trained on ~1 billion multilingual text pairs
• MIT licensed
• Works out of the box for semantic search, retrieval, clustering, and classification
• Model Family: Multilingual E5
• Architecture: XLM-RoBERTa (bidirectional Transformer encoder)
• Languages: 100+
• Task Type: Text Embedding / Sentence Similarity / Retrieval
• Max Sequence Length: 512 tokens

Example Usage

import keras_hub

# Load the text embedder with preprocessing.
embedder = keras_hub.models.TextEmbedder.from_preset(
    "multilingual_e5_base"
)

# Encode queries
query = "query: Which planet is known as the Red Planet?"
q_emb = embedder.encode_text(query)

# Encode documents/passages
documents = [
    "passage: Mars is often referred to as the Red Planet.",
    "passage: Venus is often called Earth's twin.",
]
d_embs = embedder.encode_text(documents)

# Load just the backbone for custom architectures.
backbone = keras_hub.models.XLMRobertaBackbone.from_preset(
    "multilingual_e5_base",
)
