# introduction
In the search augmentation generation (RAG) pipeline, embedded models are the foundation that makes search work. Before language models can answer questions, summarize documents, or make inferences about data, they need a way to understand and compare meanings. That’s exactly what embedding does.
In this article, we consider the top embedding models for both English-only and multilingual performance, ranked using search-focused metrics. These models are extremely popular and widely adopted in real-world systems, and consistently provide accurate and reliable search results across a wide range of RAG use cases.
Evaluation criteria:
- 60% performance: English search quality and multilingual search performance
- 30% download: Download the Hug Facial Feature Extraction Model as a Surrogate for Real-World Recruitment
- 10 percent practicality: Model size, embedding dimensions, and deployment feasibility
The final ranking favors embedded models that capture accuracy, are actively used by teams, and can be deployed without extreme infrastructure requirements.
