# Introduction
In a retrieval-augmented generation (RAG) pipeline, embedding models are the foundation that makes retrieval work. Before a language model can answer a question, summarize a document, or reason over your data, it needs a way to understand and compare meaning. That is exactly what embeddings do.
In this article, we explore the top embedding models for both English-only and multilingual performance, ranked using a retrieval-focused evaluation index. These models are highly popular, widely adopted in real-world systems, and consistently deliver accurate and reliable retrieval results across a range of RAG use cases.
Evaluation criteria:
- 60 percent performance: English retrieval quality and multilingual retrieval performance
- 30 percent downloads: Hugging Face feature extraction model downloads as a proxy for real world adoption
- 10 percent practicality: Model size, embedding dimensionality, and deployment feasibility
The final ranking favors embedding models that retrieve accurately, are actively used by teams, and can be deployed without extreme infrastructure requirements.
