Computes cosine similarity between pairs of embedded texts by taking the dot product of L2-normalized vectors, producing scores in range [-1, 1] where 1.0 indicates semantic equivalence. The normalization step is built into the embedding generation pipeline, allowing single-pass similarity computation without additional normalization overhead. Supports batch processing of multiple query-document pairs simultaneously for throughput optimization.
Unique: Embeddings are pre-normalized to unit vectors during generation, eliminating the need for post-hoc normalization in similarity computation — this design choice reduces latency for high-throughput ranking scenarios by ~15% compared to models requiring explicit normalization
vs alternatives: Faster similarity computation than sparse BM25 for large-scale ranking due to vector normalization baked into the model, while maintaining competitive NDCG scores on MTEB benchmarks
bge-large-en-v1.5 scores higher at 52/100 vs vlm_test_images at 21/100.
