notes
Encoder: kv_cache_bytes_per_token = 0, KV formula does not apply. Identical architecture to bge-large-en-v1.5 and gte-large: BERT-large, hidden 1024, 24 layers, 16 heads, intermediate 4096, vocab 30522, 512 max_position_embeddings. The E5 family's distinguishing feature is the 'query:' and 'passage:' prefix convention required at inference time — failing to add these prefixes degrades retrieval quality significantly. This is a serving gotcha: the prefix must be baked into the embedding pipeline, not added as an afterthought. MIT license. GGUF and ONNX ports exist.
