Uses absolute positional embeddings and segment embeddings to encode sequence structure and sentence boundaries.
Unique: Bidirectional transformer architecture (unlike GPT's unidirectional design) enables context-aware predictions by attending to both preceding and following tokens simultaneously; trained on 110M parameters making it lightweight enough for edge deployment while maintaining strong performance on GLUE benchmark tasks
vs alternatives: Smaller and faster than BERT-large (110M vs 340M params) with minimal accuracy trade-off, and more widely adopted than RoBERTa for fill-mask tasks due to earlier release and extensive fine-tuning examples in the community
Generates dense vector representations (768-dimensional) for input text by extracting hidden states from the final transformer layer or pooled [CLS] token. Each token receives a context-dependent embedding that captures semantic and syntactic information learned during pre-training on 3.3B tokens. Embeddings can be used for downstream tasks like semantic similarity, clustering, or as input features for classifiers without fine-tuning.
Unique: Bidirectional context encoding produces embeddings that capture both left and right linguistic context, unlike unidirectional models; 768-dim vectors offer a balance between expressiveness and computational efficiency compared to larger models (1024+ dims) or smaller models (256 dims)
