Matryoshka 嵌入模型（MRL）允許單一模型輸出多種不同維度的向量，如同俄羅斯套娃般大包小。 這項技術能讓開發者在不重新訓練模型的情況下，自由截斷維度，大幅降低向量資料庫的儲存與檢索成本。 Hugging Face 的 sentence-transformers 庫已原生支援此技術，為 RAG 與向量檢索提供極高的部署彈性。
This article provides an in-depth introduction to Matryoshka Representation Learning (MRL), also known as Matryoshka embedding models. Traditional embedding models output vectors of a fixed dimension (such as 768 or 1536 dimensions), which imposes enormous storage and computational latency costs when handling large-scale vector retrieval (RAG).
