Elastic, widely recognized as the Search AI Company, has introduced jina-embeddings-v5-text, a new family of compact, Elasticsearch-native multilingual embedding models designed to elevate search and semantic performance. With models available at 0.2 billion and 0.6 billion parameters, Elastic is positioning this release as a major advancement in efficient AI-powered retrieval.
Importantly, despite their relatively small size, these models outperform significantly larger alternatives ranging from 7 billion to 14 billion parameters. Moreover, they deliver best-in-class performance on the Multilingual MTEB (MMTEB) benchmark among models of similar size and purpose. As a result, organizations can now achieve state-of-the-art multilingual search capabilities without the heavy infrastructure burden typically associated with large language models.

Because of their compact footprint, jina-embeddings-v5-text models enable highly efficient hybrid search while lowering infrastructure costs. In addition, they accelerate query response times and unlock new deployment possibilities in memory- and compute-constrained environments. For example, enterprises can deploy these models on edge devices and in resource-limited settings where traditional large models would be impractical.
To ensure accessibility and flexibility, Elastic is making jina-embeddings-v5-text available through multiple channels. Users can access the open-weight models on HuggingFace for self-hosted deployments using vLLM, llama.cpp, or MLX. At the same time, Elastic offers the models through Elastic Inference Service (EIS), a GPU-accelerated inference-as-a-service platform that simplifies high-quality inference without requiring complex configuration. Consequently, businesses can quickly operationalize advanced multilingual embeddings without significant setup overhead.
By integrating the Jina v5 family into EIS, Elastic strengthens its unified enterprise stack. Organizations benefit from a comprehensive data platform that combines state-of-the-art multilingual embedding models with a high-performance vector database and additional AI capabilities across both cloud and on-premises environments.

“Vector search, RAG, and AI agents depend on high-quality retrieval,” said Steve Kearns, general manager, Search, Elastic. “With the addition of the Jina v5’s multilingual embeddings, Elasticsearch continues to be the platform of choice for end-to-end context engineering.”
The jina-embeddings-v5-text family includes two models: jina-embeddings-v5-text-small (239 million parameters) and jina-embeddings-v5-text-nano (677 million parameters). Notably, Elastic optimized both models for four essential tasks in search and agent-driven applications.
First, Retrieval enables users to query systems using natural language and discover the most relevant documents quickly. Second, Text Matching allows organizations to detect duplicates, align paraphrased content, and compare translations effectively. Third, Classification supports document categorization, sentiment detection, and anomaly identification. Finally, Clustering helps teams group documents based on topic, meaning, or subject matter.
Overall, with jina-embeddings-v5-text, Elastic continues to push the boundaries of efficient, multilingual AI search proving that smaller models can deliver enterprise-grade performance without compromise.
