Extracts dense vector representations (embeddings) from intermediate transformer layers to capture semantic meaning across languages in a shared embedding space. The model's 12 encoder layers produce 768-dimensional contextual embeddings for each token, with the [CLS] token serving as a sentence-level representation. These embeddings can be extracted from any layer and used for downstream tasks like semantic similarity, clustering, or as input to task-specific classifiers without fine-tuning.
Unique: Provides unified cross-lingual embedding space trained on 100+ languages simultaneously, enabling direct semantic comparison between languages without language-specific alignment or translation — unlike separate monolingual models or translation-based approaches that introduce translation artifacts
vs alternatives: Produces more semantically coherent cross-lingual embeddings than mBERT due to larger pretraining corpus and better subword tokenization, while maintaining compatibility with standard vector similarity metrics (cosine, L2) without requiring specialized distance functions
