Overview

Snowflake Arctic Embed M v1.5 is an updated embedding model released in July 2024, featuring 109M parameters (BERT architecture) with 768-dimensional vectors and a 512-token context window. It achieves an MTEB Retrieval score of 55.14 NDCG@10.

Its defining feature is vector compressibility: via Matryoshka Representation Learning (MRL), vectors can be truncated to 256 dimensions (54.2 NDCG@10, retaining 99% quality), and combined with 4-bit scalar quantization, compressed to 128 bytes per vector (53.7 NDCG@10, retaining 98% quality), enabling 7.8M vectors per GB.

Available on Snowflake Cortex AI as `snowflake-arctic-embed-m` and `snowflake-arctic-embed-m-v1.5`, on Hugging Face, via Sentence Transformers, Transformers.js, and Text Embeddings Inference. Apache 2.0 licensed for free commercial use.
